The Castell de Sant Esteve de Mar is a ruined castle perched atop a cliff in the town of Palamós, in Baix Empordà, between La Fosca and the Cala s'Alguer. Only the bases of some towers and some walls remain, and is currently surrounded by a fence that prevents access to visitors. It is accessed from the path leading from the beach of Fosca to S'Alguer that forms part of the GR 92 long distance footpath. Read more on Wikipedia
