In 1953, work began on the construction of Gavea Tourist Hotel. The idea, designed by architect Décio da Silva Pacheco, was to make a luxury establishment targeting high-earning clientele. The location encompasses about 30,000 square meters, which was to include a restaurant, a private forest and even an aerial tram. Although unfinished, the space was opened for some events: in 1965, there was a large New Year’s Eve celebration with 1,000 guests, and a night club called Sky Terrace was open for a while on the property grounds. From the 60s onward, the setting has been the backdrop for films, model shoots as well as highly frequented by curious travelers over the last decade, including for sports.
However, in March 1972, the construction of the Hotel was interrupted by developer California Investments, which would take over the project. Five years later, the company filed for bankruptcy and work stopped altogether (and gone with it, the money from 11,000 people who bought shares in the company in exchange for free stays at the hotel). In 2011 it was sold to a group of investors for R$29 million and the building was closed in preparation for technical inspections and future construction, but there were problems with permits and the project didn’t go ahead.
As mentioned, that doesn’t stop people from going there, though. In part, thanks to Globo’s article (PT) in 2016 about the location becoming a tourist spot, there have been many reports (even up to August 2017) of guards posted there and the location being effectively closed. – Sources 1 (PT), 2 (PT) and 3 (PT)
