The Castle of Pambre, located in Palas de Rei, Lugo, ranks among Galicia's finest examples of late medieval military architecture. Constructed around 1375 by Galician nobleman Gonzalo Ozores de Ulloa on a dramatic rocky hill overlooking the Pambre River, the fortress features a sophisticated quadrangular floor plan with a central homage tower and four corner towers connected by protective walls. The castle gained strategic importance protecting the nearby Camino de Santiago pilgrimage route, surviving the turbulent Irmandiña Revolt of 1467 intact. Following the 15th-century transition to the Monterrey family's ownership, the site expanded to include a traditional horréo granary and a 12th-century chapel. The Xunta de Galicia purchased and comprehensively restored the fortress between 2015 and 2016, opening it year-round to the public as a remarkable testimony to medieval Galician military heritage and defensive sophistication.
