With 128 m high and 18 floors, it was after the end of its construction in 1974, the highest architectural structure in the country, a title it kept until the inauguration of the Telefonica Tower in 1996 with 143 m. Already surpassed in height by other buildings, it continues being the structure of greater prominence in the commune of Santiago, being located next to the Avenida Libertador General Bernardo O'Higgins and to a block of the La Moneda Palace, adding to the rationale behind its iconic status in the city.
From that moment on, the Entel Tower became the vital nucleus of the country's communications system by allowing the interconnection of Entel's telephone, television, radio and microwave network services with those of the Chilean Telephone Company (currently Movistar) and with the north, center and south of the country and the province of Mendoza, Argentina.
Currently, all the equipment that carries international traffic via satellite, the Santiago-Mendoza terrestrial, the southern and northern National Trunk networks operate there, and it interconnects the public long-distance telephone, telex, television and radio broadcasting services.
On the night of December 31, 2009, the largest LED screen in South America was inaugurated and installed at the top of the tower to mark the "Bicentennial New Year".
[2] The Entel Tower is 127.40 m high from its base and is located at the intersection of the Alameda del Libertador Bernardo O'Higgins and Amunátegui, next to the La Moneda station of the Santiago Metro as this is a strategic place due to the proximity of the sites where connections to the urban telephone network are made.
