In which year was the Old Stockholm telephone tower demolished?

In 1887, Stockholms Allmänna Telefon AB ordered the construction of a tower allowing the connection of about 5,500 overhead telephone lines. The quadrangular metallic structure was 80 metres tall and soon fell out of favour with the local population. The company requested the architect Fritz Eckert to carry out embellishment work, which was when the four turrets were added.

The tower was quickly made obsolete as telephone companies began using underground cables in urban areas. In 1913, underground cabling for telephony was fully completed and the tower no longer served its original purpose. After 1939 it carried advertising for the telephone company, and on 23 July 1952 a fire weakened the structure, resulting in its demolition in 1953 on safety grounds.
