Castelo do Bolo is a 12th-century fortress located in O Bolo within the Valdeorras region of Galicia, Spain. Originally built in 1092 and destroyed during the Irmandiño Revolts of the 15th century, the castle was subsequently rebuilt by order of Juan de Pimentel, Count of Benavente. The Torre do Bolo today houses an Interpretation Center providing visitors with insights into 15th-century military life, construction techniques, and the historical context of this important Galician stronghold that once belonged to the Counts of Lemos.
