Obelisco di Marconi (Marconi Obelisk), Rome

The Marconi Obelisk, also known as the Obelisk of EUR, is considered one of the most contemporary obelisks in Rome, alongside the Obelisco Novecento and the obelisks of the Foro Italico, Villa Torlonia, and Villa Medici. Originally intended to adorn Piazza Imperiale, which was planned to be the central square of the newly developed district according to the project for the 1942 World's Fair in Rome, the obelisk was also meant to commemorate physicist, inventor, and senator Guglielmo Marconi, famous for his development of the radio telegraph system, who had passed away two years prior. The monument was finally completed and inaugurated in December 1959.

The Marconi Obelisk stands at the center of the square, which is now named after Guglielmo Marconi. The structure itself takes the form of a truncated pyramid, constructed using reinforced concrete covered by 92 Carrara marble slabs. These marble slabs feature high relief carvings arranged in four rows, adding artistic intricacy to the monument.
