Admiring this horseshow arch? The honeycomb design in the ceiling is exquisite. This is a form of Islamic architecture called a muqarnas vault. Beginning in 1332, this was an entrance to a place for traveling merchants to sleep and eat while selling their wares to commoners during their stay in Granada. The Muslim name was Alhóndiga Nueva. In the early 16th century, the Christian’s renamed it Corral del Carbón. Now walk inside. Sense the commotion that once surrounded the fountain in the courtyard. Look at the three levels of rooms. Imagine staying at this merchant hotel during the Middle Ages.
