 In 1956, the roof was repaired, including the substitution of broken tiles, repairs to the battlements, frames and substitution of broken windows, while another group of public works were made to transition the structure for reuse, such as the installation of an electrical system, arrangement and painting of the door, construction of a new staircase, and the re-landscaping of the terrain around it, including leveling the terrain, paving with gravel and planting flowerbeds.The tower, thus, became the headquarters for the"Delegação da Sociedade Histórica da Independência de Portugal" ("Delegation of the Historical Society of Portuguese Independence") in 1957.A year later, on the celebration of the commemorations associated with the establishment of the Portuguese monarchy (), the Portuguese Mocidade erected a commemorative plaque alongside the tower.
