Bonaria Museum

Tucked next to the famous Sanctuary of Our Lady of Bonaria, this small museum sits inside an Aragonese-era building on the hill that overlooks the sea. It traces the layered history of Bonaria hill itself — from ancient times through the Mercedari order who settled here — with artifacts and testimonies that most people walk right past on their way to the church. Quietly fascinating if you're into the kind of local history that doesn't make it into the guidebooks.
