In the autonomous community of Castile and Leon, near the city of Valladolid, sits the impressive Castillo de Peñafiel. This stone fortress, built on a rocky hill with a tall central square tower, is a prime example of Iberian German Gothic architecture. The castle stretches 210 meters in length and 33 meters in width, with its main tower, the Torre del Homenaje, standing 30 feet tall and overseeing two inner courtyards.

The origins of the castle date back to the ninth century, but it gained its grand appearance in the fifteenth century under Don Pedro Téllez Girón. He transformed it into a critical defensive structure overlooking the Duero and Duratón rivers and the Botijas valley. Recognized as a National Monument since 1917, the castle became the home of the Provincial Wine Museum of Valladolid in 1999. This initiative by the Diputación of Valladolid aimed to promote the region through wine, attracting visitors to explore the local wine routes.

For those interested in religious architecture, the Convent of San Pablo is a must-visit. Built in 1324 on the remnants of a fortress constructed by Alfonso X, the convent features a mix of Gothic and other architectural styles and houses the mausoleum of Don Juan Manuel de Villena.

The Castillo de Peñafiel is open from October 1st to March 31st, Tuesday to Sunday, from 11:30 to 14:00 and 16:00 to 19:00. It is closed on Mondays. Admission to the museum and castle is 6 Euros, with an additional guided tour of the castle available for 3 Euros.
