Helicoide de Caracas (Roca Tarpeya) (Caracas)

Designed by Architect Jorge Romero, it was meant to be a Shopping Center. It was abandoned because of political reasons, and left unfinished and vacant for decades. Several proposals were made for its use after completion, including a heliport (late 60s), headquarters for the Ministry of the Environment (early 90s), and a community center (late 90s). Eventually it became the headquarters for the DISIP (internal intelligence agency / political police), which has long had a reputation for abuse and human-rights violations.
