Palace of la Serreta Monument · Lastras de Cuéllar, Tierra de Pinares, Segovia Image of Lastras de Cuéllar, not of the place itself. La Serreta was a hamlet of the Comunidad de Villa y Tierra de Cuéllar, documented since 1138 and already depopulated by 1751, located south-southwest of Lastras de Cuéllar beside the river Cega. In the 15th century, Beltrán de la Cueva, favourite of Henry IV of Castile and first Duke of Alburquerque, lord of Cuéllar, had a palace built there that still stands, together with the San Antón hermitage, and created around it one of the oldest hunting estates in Spain, where King Juan Carlos I once hunted. The estate, amid pine woods and far from any inhabited settlement, also preserves a traditional river-crab fishing reserve. In 2018 it was sold for 19 million euros to a company that is promoting there the recovery of the European bison, with 18 specimens since 2019.
