Telecom Italia Tower - Naples - was created in 1995.
If you are referring to the British Telecom Tower in central London - which used to be called the Post Office Tower - it's 620 feet or 189 metres tall.
Work on the tower started in 1961, with the then Prime Minister, Harold Wilson, officially opening the 'Post Office Tower' on October 8th, 1965 with a ceremonial call to the Lord Mayor of Birmingham. (The tower is now known as the 'BT Tower' or 'British Telecom Tower'). Bizarrely, Sir Billy Butlin and Tony Benn joined together on May 19 1966 to open the 'Top of the Tower' restaurant. The tower was an immediate hit with the public, attracting 1.5 million visitors in the first year. The British Telecom Communication Tower in London's West End was the first purpose-built tower to transmit high frequency radio waves, and it serves as a functional telecommunications centre designed to relay broadcast, Internet and telephone information around the world. Built to cater for the UK's growing telecommunications requirements, Telecom Tower was designed by a team led by G R Yeats under the direction of Eric Bedford, chief architect of the Ministry of Public Buildings and Works. The principal building contractors were Peter Lind & Co.
The British Telecom Communication Tower in London was completed in 1964. With a spire reaching a height of 191 meters (627 feet), it was the tallest building in London until superseded by the NatWest Tower in 1980.
