The Castle of Cardona is probably the most important medieval fortress in the province of Catalunya. It is situated on a hill overlooking the river valley of the Cardener and the town of Cardona. The fortress was initially constructed by Wilfred the Hairy in 886. It is in both the Romanesque and Gothic styles, and includes the so-called Sala Dorada and Sala dels Entresols. During the 14th century, the dukes of Cardona came from the most important family of the Crown of Aragon, which was second only to the royal house. Because of this, they were called 'kings without crowns' as they had extensive territories in Catalunya, Aragon, and Valencia, and dynastic ties with Castile, Portugal, Sicily, and Naples. This presumably increased the importance of the fort. In 1714, even after a Bourbon siege destroyed a good part of the fort's walls, the garrison was one of the last to surrender to the Bourbon troops which supported Philip V. As the Bourbons and their heirs would go on to suppress Catalonian national identity, the fort has become significant to Catalonian nationalism. Today, the fort's main jewel is the torre de la minyona (from the 11th century) a tower which measures 15 meters in height and 10 meters in diameter. Additionally, there is the romanesque church of Sant Vicenç de Cardona adjacent to the fort. The fort is currently used as a parador, or state-run luxury hotel.
