After the closure in 2015 of the Instituto de Odivelas, the site was abandoned. Following this the Municipality of Cascais signed an agreement aimed at transferring the site to the municipality, which intended to use it as a research centre, at an estimated cost of €6mn. The transfer finally took place in March 2018 and the fort was opened for public viewing on April 25, 2018, Freedom Day in Portugal, which celebrates the overthrow of the authoritarian regime of the Estado Novo in 1974. In 2016, a fire had been reported in one of the areas of the fort. The fort also suffered internal damage and had been the victim of significant graffiti.
