This 14th-century barn in the grounds of Conwy Castle, Wales, is a rare surviving example of a medieval hall house. Its name "Spanish" is believed to come from the dark red color of the stone used in its construction, which resembles the color of Spanish leather. The barn's architecture is a mix of English and Welsh influences, featuring a large, open hall with a high, timber-framed roof, and a series of doorways and windows that let in natural light. The building's historic significance and picturesque setting make it a popular tourist destination.
