The Castillo del Bil-Bil is a small terracotta-coloured castle on the seafront, built in 1934 as a private villa in a romantic neo-Arabic style. It looks like something from a North African film set and is one of the more photogenic buildings on the coast.
Today it belongs to the town and hosts art exhibitions, cultural events, and the occasional wedding. The garden is open to the public and you can walk around the building for free; check the Benalmádena website for current exhibition openings.
