                                       3

                     This Amendment No. 29 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

                     On April 6, 2004, Pirelli & C. exercised its call option to
acquire 47,155,300 Telecom Italia Shares from J.P. Morgan Chase & Co. at an
exercise price per share of euro 2.12. (The call option is described in Item 4
of Amendment No. 7 to the Statement on Schedule 13D.) Settlement of the
transaction is expected to occur prior to the end of April 2004. A copy of a
press release issued by Pirelli & C. in connection with the transaction is filed
as Exhibit 61.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

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