The Convento de San Marcos was a convent in León, Spain, that is today an operating luxury parador hotel. It also contains a consecrated church and museum, and is one of the most important monuments of the Renaissance in Spain. It is one of the greatest architectural jewels of León, together with the Cathedral, the Basilica of San Isidoro and la Casa Botines. It has a highly ornamental plateresque facade.
The darkest period in the monastery of San Marcos's five centuries of history is concentrated in just four years. During the course of the Spanish Civil War cells, rooms, stables, cloisters, church, choir, museum and every fast corner of the building were transformed into impromptu dungeons or jailers' offices, in what became officially known as "Campo de concentración de San Marcos".
