Av. Berlín, 51, 38379 La Matanza de Acentejo, Santa Cruz de Tenerife, Spain
This abandoned building called by the locals El Esqueleto (meaning “the skeleton” in Spanish) is a hotel project from the 1970s which was never completed. High on a hill, almost balancing on the edge, stands this 15-storey wall-less structure, the closest thing to a skeleton. A somewhat controversial place as it ruins the seaview for the nearby residents who have been asking for its demolition for years, but it is still there.
Below, there is a constructed path (Paseo Costa del Sauzal, about 45-60 min) offering lovely views of the sea and the coast. Look out for traces of the old fishing towns that used to be located here in the rock formations.
