The tower was built in 1874, during the Third Carlist War, on the former site of the Ciutat redoubt. Also called the Sant Narcís or Estudiants Tower, it was built in 1575 as one of the forward positions of the Conestable Fort and blown up by the French troops in 1814, at the end of the Peninsular War. During the Spanish Civil War, anti-aircraft guns were mounted nearby because of its excellent location.
On 28 June 1928, the State authorised installation of a water deposit inside the tower.
In 1953, ownership was transferred to Girona City Council and it continued to be used as a water deposit until the 1960s.
A few years later, a television repeater was erected at the site, to be dismantled in 1982 when the Rocacorba repeater came into service.
