SUMMARY OF ESSENTIAL INFORMATION
(Continued)
THE TRUST -- The Dean Witter Select Municipal Trust,
Long Term Portfolio Series 117 (the "Trust") is a unit
investment trust which was created on January 9, 1992 (the
"Date of Deposit"), and is composed of "investment grade"
long-term interest-bearing municipal bonds (the "Securities").
(For a description of the meaning of "investment grade"
securities, see: "Bond Ratings", in Part B.) The objectives
of the Trusts are: (1) the receipt of income which, under
existing law, is excludable from gross income for Federal
income tax purposes (except in certain instances depending on
the Unit Holders) and (2) the conservation of capital. The
payment of interest and the preservation of principal in the
Trust is dependent on the continuing ability of the respective
Issuers of the Securities to meet their obligations to pay
principal and interest. Therefore, there is no guarantee that
the objectives of the Trust will be achieved. All of the
Securities are obligations of states, or of the counties,
municipalities or public authorities thereof. Interest on the
Securities, in the opinion of bond counsel or special tax
counsel to the Issuers thereof, under existing law, is
excludable from gross income for Federal income tax purposes
(except in certain instances depending on the Unit Holders).
(For a discussion of certain tax aspects of the Trust, see:
"Tax Status", in Part B.
OFFERS TO SELL OR THE SOLICITATION OF ORDERS TO BUY
MAY ONLY BE MADE IN THOSE JURISDICTIONS IN WHICH THE UNITS OF
THIS TRUST HAVE BEEN REGISTERED. INVESTORS SHOULD CONTACT
ACCOUNT EXECUTIVES OF THE SPONSOR TO DETERMINE WHETHER THE
UNITS OF THIS TRUST HAVE BEEN REGISTERED FOR SALE IN THE STATE
IN WHICH THEY RESIDE.
MONTHLY DISTRIBUTIONS -- Monthly distributions of
principal, premium, if any, and interest received by the Trust
will be made on or shortly after the fifteenth day of each
month to Unit Holders of record on the ninth day of such month.
Alternatively, Unit Holders may elect to have their monthly
distributions reinvested in either of the Reinvestment Programs
of the Sponsor. (See: "Reinvestment Programs", in Part B.)
PUBLIC OFFERING PRICE -- The Public Offering Price
per Unit of the Trust is calculated daily, and is equal to the
aggregate bid side evaluation of the underlying Securities,
divided by the number of Units outstanding, plus a sales charge
calculated by reference to "Sales Charge/Volume Discount",
below, plus the per Unit balance in the Interest and Principal
Accounts. Units are offered at the Public Offering Price, plus
A-4
<PAGE>
accrued interest. (See: "Public Offering of Units", in
Part B.)
ESTIMATED CURRENT RETURN -- The Estimated Current
Return shows the return based on the Public Offering Price and
is computed by multiplying the estimated net annual interest
rate per Unit (which shows the return based on a $1,000 face
amount) by $1,000 and dividing the result by the Public
Offering Price (not including accrued interest). The net
annual interest rate per Unit will vary with changes in the
fees and expenses of the Trustee, the Sponsor and the Evaluator
and with the exchange, redemption, sale or maturity of the
underlying Securities. In addition, the Public Offering Price
will also vary with fluctuations in the bid side evaluation of
the underlying Securities. Therefore, it can be expected that
the Estimated Current Return will fluctuate in the future.
(See: "The Units -- Estimated Annual Income and Current
Return", in Part B.)
MARKET FOR UNITS -- The Sponsor, though not obligated
to do so, intends to maintain a market for the Units based on
the aggregate bid side evaluation of the underlying Securities,
as more fully described in Part B -- "Public Offering of Units
- -- Secondary Market". If such market is not maintained, a Unit
Holder will be able to dispose of its Units through redemption
at prices based on the aggregate bid side evaluation of the
underlying Securities. (See: "Redemption", in Part B.)
Market conditions may cause such prices to be greater or less
than the amount paid for Units.
SPECIAL CONSIDERATIONS -- An investment in Units of
the Trust should be made with an understanding of the risks
which an investment in fixed rate long term debt obligations
may entail, including the risk that the value of the Units will
decline with increases in interest rates. The Trust is
considered to be concentrated in Prerefunded/Escrowed to
Maturity Securities (46.31%, of the aggregate market value of
the Trust). (See: "The Trust -- Special Considerations" and
"The Trust -- Summary Description of the Portfolios", in
Part B. See also: "Special Characteristics of the Trust",
herein, for a discussion of additional risks relating to Units
of the Trust.)
SPECIAL CHARACTERISTICS OF THE TRUST -- The Portfolio
of the Trust consists of twelve issues of Securities, which
were issued by Issuers located in ten states. One of the
issues of Securities is a general obligation of an Issuer.
Eleven issues of Securities, while not backed by the taxing
power of the Issuer, are payable from revenues or receipts
derived from specific projects or other available sources. The
Trust contains the following categories of Securities:
A-5
<PAGE>
Percentage of Aggregate
Market Value of Trust Portfolio
Category of Security (as of February 7, 1997)
Electric and Power .............. 12.56%
Health Care and Hospital ........ 15.53%
Housing ......................... 20.27%
Prerefunded/Escrowed

State Appropriation.............. 5.33%
Original Issue Discount ......... 58.93%
See: "The Trust -- Summary Description of the
Portfolios", in Part B, for a summary of the investment risks
associated with the type of Securities contained in the Long
Term Uninsured Trust. See: "Tax Status", in Part B, for a
discussion of certain tax considerations with regard to
Original Issue Discount.
Of the Original Issue Discount bonds in the
Trust, approximately 3.96% of the aggregate principal amount of
the Securities in the Trust (or 1.17% of the market value of
all Securities in the Trust on February 7, 1997) are zero
coupon bonds (including bonds known as multiplier bonds, money
multiplier bonds, capital accumulator bonds, compound interest
bonds and discount maturity payment bonds).
Securities representing approximately 15.61% of the
aggregate market value of the Portfolio are currently subject
to redemption from mandatory sinking fund payments. Securities
representing approximately 12.56% of the aggregate market value
of the Portfolio are currently subject to redemption at the
option of the Issuer thereof. Securities representing
approximately 12.56%, 0%, 0% and 15.61% of the aggregate market
value of the Portfolio are subject to redemption at the option
of the Issuer thereof beginning in 1997, 1998, 1999 and 2000,
respectively. (See: "Schedule of Portfolio Securities,"
herein, and "The Trust -- Summary Description of the
Portfolios -- Additional Securities
Considerations -- Redemption of Securities," in Part B.)
On February 7, 1997, based on the bid side of the
market, the aggregate market value of Securities in the
Portfolio Trust was $4,555,575.13.
The Securities in the Portfolio of the Trust were
chosen in part on the basis of their respective maturity dates.
A long term Trust contains obligations maturing in 15 years or
more from the Date of Deposit. The maturity date of the Trust
is January 2041; the latest maturity of a Security therein is
January 1, 2024; and the average life to maturity (or date of
pre-refunding of a bond) of the Portfolio of Securities therein
A-6
<PAGE>
is 15.389 years. The actual maturity dates of each of the
Securities contained in the Portfolio are shown on the
"Schedule of Portfolio Securities", herein.
The Trustee shall receive annually 72 cents per
$1,000 principal amount of Securities in the Portfolio for its
services as Trustee. See: "Expenses and Charges", in Part B,
for a description of other fees and charges which may be
incurred by the Trust.
On February 7, 1997, Standard & Poor's Corporation
rated seven of the Securities in the Trust as follows:
29.89%-AAA and 15.53%-BBB; and Moody's Investors Service rated
four of the Securities as follows: 29.67%-Aaa and 9.30%-Baa-1.
15.61% of the Securities are not rated; however, in the opinion
of the Sponsor, these Securities have credit characteristics
comparable to investment grade securities. (See: the
respective "Schedule of Portfolio Securities", herein, and
"Bond Ratings", in Part B.) A Security in the Portfolio may
subsequently cease to be rated or the rating assigned may be
reduced below the minimum requirements of the Trust for the
acquisition of Securities. While such events may be considered
by the Sponsor in determining whether to direct the Trustee to
dispose of the security (see: "Sponsor -- Responsibility", in
Part B), such events do not automatically require the
elimination of such Security from the Portfolio.
SALES CHARGE/VOLUME DISCOUNT -- The Public Offering
Price per Unit will be computed by dividing the aggregate of
the bid prices of the Securities in a Trust by the number of
Units outstanding and then adding the appropriate sales charge
described below.
The sales charge will reflect different rates
depending upon the maturities of the various underlying
Securities. The sales charge per Unit in the secondary market
(the "Effective Sales Charge") will be computed by multiplying
the Evaluator's determination of the bid side evaluation of
each Security by a sales charge determined in accordance with
the table set forth below based upon the number of years
remaining to the maturity of each such Security, totalling all
such calculations, and dividing this total by the number of
Units then outstanding. In calculating the date of maturity, a
Security will be considered to mature on its stated maturity
date unless: (a) the Security has been called for redemption
or funds or securities have been placed in escrow to redeem it
on an earlier call date, in which case the call date will be
deemed the date on which such Security matures; or (b) the
Security is subject to a mandatory tender, in which case the
mandatory tender date will be deemed the date on which such
Security matures.

The Effective Sales Charge per Unit for a sale in the
secondary market, as determined above, will be reduced on a
graduated scale for sales to any single purchaser on a single
day of the specified number of Units of a Trust set forth
below.
Dealer Concession
% of Effective as % of Effective
Number of Units Sales Charge Sales Charge

250-499.................... 85% 55%
500-999.................... 70% 45%
1,000 or more.............. 55% 35%
To qualify for the reduced sales charge and
concession applicable to quantity purchases, the selling dealer
must confirm that the sale is to a single purchaser, as
described in "Volume Discount" in Part B of the Prospectus.
Units purchased at an Effective Sales Charge (before
volume purchase discount) of less than 3.089% of the Public
Offering Price (3.187% of the bid side evaluation of the
Securities) will not be eligible for exchange at a reduced
sales charge described under the Exchange Option.

INDEPENDENT AUDITORS' REPORT
THE UNIT HOLDERS, SPONSOR AND TRUSTEE
DEAN WITTER SELECT MUNICIPAL TRUST
LONG TERM PORTFOLIO SERIES 117
We have audited the statement of financial condition and schedule of
portfolio securities of the Dean Witter Select Municipal Trust Long Term
Portfolio Series 117 as of December 31, 1996, and the related statements of
operations and changes in net assets for each of the three years in the
period then ended. These financial statements are the responsibility of the
Trustee (see Footnote (a)(1)). Our responsibility is to express an opinion
on these financial statements based on our audits.
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements.
Our procedures included confirmation of the securities owned as of
December 31, 1996 as shown in the statement of financial condition and
schedule of portfolio securities by correspondence with The Chase Manhattan
Bank, the Trustee. An audit also includes assessing the accounting
principles used and the significant estimates made by the Trustee, as well
as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Dean Witter Select
Municipal Trust Long Term Portfolio Series 117 as of December 31, 1996, and
the results of its operations and the changes in its net assets for each of
the three years in the period then ended in conformity with generally
accepted accounting principles.

(a) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
The Trust is registered under the Investment Company Act of 1940 as a
Unit Investment Trust. The following is a summary of the significant
accounting policies of the Trust:
(1) Basis of Presentation
The Trustee has custody of and responsibility for all accounting and
financial books, records, financial statements and related data of
the Trust and is responsible for establishing and maintaining a
system of internal controls directly related to, and designed to
provide reasonable assurance as to the integrity and reliability
of, financial reporting of the Trust. The Trustee is also
responsible for all estimates and accruals reflected in the Trust's
financial statements. The Evaluator determines the price for each
underlying Security included in the Trust's Portfolio of Securities
on the basis set forth in Part B of this Prospectus, "Public
Offering of Units - Public Offering Price". Under the Securities
Act of 1933 ("the Act"), as amended, the Sponsor is deemed to be an
issuer of the Trust Units. As such, the Sponsor has the
responsibility of an issuer under the Act with respect to financial
statements of the Trust included in the Trust's Registration
Statement under the Act and amendments thereto.
(2) Investments
Investments are stated at market value as determined by the
Evaluator based on the bid side evaluations on the last day of
trading during the period, except that value on the date of deposit
(January 9, 1992) represents the cost of investments to the Trust
based on the offering side evaluations as of the day prior to the
date of deposit.
(3) Income Taxes
The Trust is not an association taxable as a corporation for Federal
income tax purposes; accordingly, no provision is required for such
taxes.
(4) Expenses
The Trust pays annual Trustee's fees, including estimated expenses,
Evaluator's fees, and annual Sponsor's portfolio supervision fees
and may incur additional charges as explained under "Expenses and
Charges - Fees" and "- Other Charges" in Part B of this Prospectus.
