Ciudad Rodrigo Castle, also known as the Alcázar of Enrique II, stands in Spain's Salamanca province as a striking example of 14th-century military architecture. King Enrique II commissioned this fortress in 1372, positioning it strategically on the city's most difficult terrain. The castle's distinctive tower del homenaje features three levels with pointed arch windows and is surrounded by defensive walls and towers reinforced in 1506. Since 1931, it has operated as a Parador Nacional de Turismo, offering visitors the unique experience of lodging within this medieval stronghold while exploring centuries of regional history.
