Llotja de Palma, Palma's 15th-century Gothic exchange, looks exactly like a church. It isn't. Built in 1428 by Majorcan architect Guillermo Sagrera, it was designed to handle something altogether more worldly: the commerce of ships arriving after months at sea.

Before a broad coastal avenue reshaped the waterfront in the 1960s, the sea lapped right up to Llotja de Palma's walls. Merchants would moor here, then step inside to declare their cargo and fix prices with buyers. Above the entrance, a carved angel watched over it all, the sailors' guardian, thanked in person by those who'd made it home alive.

VoiceMap's self-guided audio tours trace the Llotja's role in Palma's maritime economy, explaining how the coastline itself has changed and connecting the building to the layered medieval quarter that grew up around it.
