Cuéllar Castle
Castillo de Cuéllar
Cuéllar Castle (Castle of the Dukes of Alburquerque) crowns the highest hill of the town of Cuéllar in Segovia, Spain. Built and modified between the 13th and 18th centuries, it was transformed in the 16th century into the dukes' Renaissance palace while retaining military curtain walls and towers. The monument is conserved in good condition following 20th-century restoration and today stands as the town's emblematic fortress-palace.

As it stood in 1560
What Cuéllar Castle looked like in its prime.
Perched on the town's highest point, the castle presents a long pale limestone curtain wall punctuated by round and square towers and crenellated battlements. A dominant, tall cylindrical keep with a machicolated crenel top rises above lower circular flanking towers. To one side the ducal palace block shows steep tiled roofs and rectangular windows set into ashlar masonry. The main approach is a broad stepped plaza leading up to a fortified gate set into the curtain, all in sound stonework.
Its story
The story of Cuéllar Castle.
Cuéllar's walled enclosure appears in documents from 1264, when Alfonso X the Wise let the town council spend the proceeds of fines on its repair; the first record of the castle itself dates from 1306, under Ferdinand IV. Built in styles from Gothic to Renaissance between the thirteenth and eighteenth centuries, it passed through the hands of Álvaro de Luna and Beltrán de la Cueva before becoming the seat of the successive Dukes of Alburquerque.
The sixteenth century turned the military building into the Dukes' Renaissance palace, with masters including Juan Guas, Hanequin of Brussels and Rodrigo Gil de Hontañón at work on it. Castilian monarchs stayed within its walls, Juan I's queen, Leonor of Aragón, died here, and María de Molina took refuge in the castle when her kingdom was rejecting her, and during the Peninsular War the Duke of Wellington set his garrison barracks in it.
When the Dukes moved to Madrid to be near the court the castle slid into abandonment and, by the late nineteenth century, robbery. In 1938 a political prison was created inside it, later a sanatorium for prisoners with tuberculosis, and it remained a prison until 1966. An intensive restoration in 1972 made it the home of a vocational education school, which continues to this day.
