The Corral del Carbón is Granada's best-kept open secret: a Nasrid building from the 1300s, tucked behind an ornate horseshoe arch just off the city centre. It was built by Sultan Yusuf I as an alhóndiga, a warehouse where wheat was stored and traded, with merchants sleeping in small rooms on the upper floors and their animals tied up below. After the Castilian conquest of 1492, it changed hands repeatedly, became a theatre, then a coal store, and by the time it was declared a National Monument in 1887, thirty-six families were crammed inside.

Today it belongs to the Dobla de Oro collection, managed by the Alhambra, and admission is free. VoiceMap's self-guided tours of Granada trace the building's journey from Islamic trading post to Christian theatre to near-demolition, placing it within the wider story of 1492 and the layered histories written into Granada's city centre.
