Cuéllar’s history stretches back to ancient times, with evidence of Roman and pre-Roman settlements in the region. However, the city is best known for its medieval heritage, with significant Moorish and Christian influences shaping its development. During the Reconquista, Cuéllar became an important frontier town, and its defensive structures, including its famous castle, were built during this period. The Castle of Cuéllar, a 12th-century fortress that has undergone many renovations over the centuries, is one of the most well-preserved castles in Spain and a key tourist attraction.
The city’s cultural life is vibrant, with traditions deeply rooted in its medieval past. One of Cuéllar’s most famous events is the “Encierros de Cuéllar,” a bull-running festival that takes place every year in late August and is considered one of the oldest in Spain. In addition to this thrilling event, the city is known for historical re-enactments and performances that celebrate its heritage. Local festivals, often featuring medieval themes, bring the town’s streets to life with parades, music, and traditional costumes.
