Pancorbo Castle: 9th-Century Fortress Overlooking a Spanish Gorge, Burned in

The 9th-century Pancorbo Castle stands over Pancorbo gorge in Spain's Burgos province. It was strategically positioned to protect the entrance to one of the country's most impressive gorges. Built by Diego Porcelos in the late 9th century, it was known under several names over the centuries: Santa Marta, Pancorbo, and La Sala. It was besieged but never captured by Al-Mundir in 882, but passed into the hands of Navarrese nobles in the 11th century and was later possessed by the Castle of Burgos. In the 16th century, Diego Gómez de Sarmiento stole the castle and kept it until the early 16th century. In 1679, visitors from France described it, but in August 1835, it was burned during the First Carlist War. Today, only a few ruins remain, with a bridge between the rocks once holding the castle walls.
