                                       3

           This Amendment No. 30 amends the Statement on Schedule 13D, dated
August 9, 2001, as amended (as previously amended, the "Statement on Schedule
13D"), filed by Pirelli S.p.A. (which, as reported in Amendment No. 21 to the
Statement on Schedule 13D, subsequently merged with and into Pirelli & C.
S.p.A., a company incorporated under the laws of the Republic of Italy), and,
commencing with Amendment No. 1 thereto, Olimpia S.p.A., a company incorporated
under the laws of the Republic of Italy, with respect to the ordinary shares,
euro 0.55 par value per share, of Telecom Italia S.p.A., a company incorporated
under the laws of the Republic of Italy. Capitalized terms used in this
Amendment without definition have the meanings ascribed to them in the Statement
on Schedule 13D.

           Pirelli & C., Olimpia, Edizione Holding and Edizione Finance, Hopa,
UCI and BCI are members of a group with respect to the Telecom Italia Shares.
This Amendment constitutes a separate filing on Schedule 13D by Pirelli & C. and
Olimpia in accordance with Rule 13d-1(k)(2) under the Securities Exchange Act of
1934. Pirelli & C. and Olimpia are responsible solely for the information
contained in their separate filing, except that information contained in the
Statement on Schedule 13D concerning any director or officer of Olimpia
nominated by Edizione Holding, Hopa, UCI or BCI has been provided by the
nominating person or by such nominee director or officer.

ITEM 3.    SOURCE AND AMOUNT OF FUNDS AND OTHER CONSIDERATION

           Reference is made to Item 3 of Amendment No. 29 to the Statement on
Schedule 13D, wherein it was reported that, on April 6, 2004, Pirelli & C.
exercised its call option to acquire 47,155,300 Telecom Italia Shares from J.P.
Morgan Chase & Co. Settlement of the transaction was effected on April 19, 2004
by Pirelli Finance Luxembourg S.A. ("PFL"), a wholly-owned subsidiary of Pirelli
& C., which purchased the Telecom Italia Shares from J.P. Morgan Chase & Co. for
an aggregate purchase price of euro 100,000,000. PFL used its own funds to
purchase the Telecom Italia Shares.

ITEM 4.    PURPOSE OF TRANSACTION

           On April 19, 2004, Olimpia announced its proposal that certain
resolutions be adopted at an ordinary meeting of shareholders of Telecom Italia
to be held on May 5 and May 6, 2004 (the "2004 Shareholders' Meeting"). Among
other things, Olimpia proposes that (i) the number of directors of Telecom
Italia be increased from fifteen to nineteen, (ii) the directors of Telecom
Italia elected at the 2004 Shareholders' Meeting shall hold office for a period
of three years and (iii) a "slate" of nineteen candidates be elected to the
board of directors of Telecom Italia. A copy of the announcement issued by
Olimpia (which includes the name of each of the persons on Olimpia's slate of
candidates for election to the board of directors of Telecom Italia) is filed as
Exhibit 62.

ITEM 5.    INTEREST IN SECURITIES OF THE ISSUER

           After giving effect to the acquisition by PFL of the 47,155,300
Telecom Italia Shares referred to in Item 3, Pirelli & C. may be deemed to
beneficially own 1,798,921,123 Telecom Italia Shares (including the
1,751,765,823 Telecom Italia Shares beneficially owned by Olimpia), representing


                                       4

approximately 17.46% of the total number of Telecom Italia Shares reported to be
issued and outstanding.

ITEM 6.    CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
           TO SECURITIES OF THE ISSUER

           Reference is made to the New Partners Agreement (as that term is
defined in Item 3 of Amendment No. 2 to the Statement on Schedule 13D). On April
24, 2004, Pirelli & C., UCI and BCI filed a notice with Consob, the Italian
securities regulator, which reports that the term of the New Partners Agreement
has automatically been extended until October 4, 2006. A copy of the notice is
filed as Exhibit 63. The initial term of the New Partners Agreement expires on
October 4, 2004, but the agreement is automatically renewed for a period of two
years if notice of termination is not given by any party thereto six months
prior such date.

62.        Announcement of Olimpia, dated as of April 19, 2004.
