The Palacio Real (Royal Palace) of Olite, the seat of the Court of Navarre until its union with Castile (1512), was one of the most luxurious mediaeval castles in Europe. The Royal Palace of Olite, in the province of Pamplona, is proof of the splendour of the Court that Olite hosted during the Middle Ages. It covers one-third of the old part of the town and is considered one of the most interesting Gothic complexes in Europe.
