These impressive battlements date back millennia. Started by the Phoenicians and then further developed by the Arabs, Gibralfaro has been defending Malaga in Spain for a long time. They are a huge, well-build and well-designed defence, created by intelligent and capable people. No ancient primitives here.
It’s a long climb up the hill from the city centre to get to them, but definitely worth the effort to walk where people have walked for thousands of years.
