Castle of Burgos

The Castle of Burgos was a castle and alcázar, located in the city of Burgos, in the hill of San Miguel to 75 metres above the city and to 981 metres above the sea. This hill was the subject of archaeological surveys by General Centeno in the years 1925 and 1926 trying to find Napoleonic military files from when the French in their retreat blew up the fortress. According to the results obtained in this excavation the origin of the castle dates to the Visigoths, and its oldest parts, to the Romans.

The castle grew over the centuries, becoming a major fortification and residence of the kings of Castile. Following the accession of the Habsburg family the castle lost its importance as a royal residence, and during the French occupation, on June 15, 1813, the French army decided to leave the Castle of Burgos, and they destroyed it with explosives. The explosion resulted in the almost total destruction of all the castle grounds. The castle remains in ruins.
