The construction of the Palace of Fefiñáns began in the XVI century by order of Juan Sarmiento y Valladares, lord of Fefiñáns and counselor of Felipe II, the work was finished by his nephew Gonzalo de Valladares, I Fefiñáns Viscount, title given by Felipe IV , and his son Fernando Valladares II Viscount of Fefiñáns in the XVII century.
Later it was transfered by marriage ties to the Counts of Figueroa.
The Palace has a clear influence of Italian Renaissance architecture, especially evident in the composition of the facades, it has L-shaped with two beautiful circular balconies on both sides of the edifice. Two large access gates, and over them two big family coats of family lines, introduced by Fernando Valladares embellish the front of the spectacular edifice. The north side of the Palace is dedicated to Fernando Valladares and the west side to Gonzalo.
A great battlement tower and an arch-bridge in trace baroque in the north side of the Palace, aforetime accompanied by other three, complement the architectural ensemble.
Nowadays, in the basement of the palace are located two Albariño wine cellars: the “Joaquín Gil Armada” wine cellar and the “Palacio de Fefiñanes” wine cellar; Fefiñáns wine cellar was the first wine cellar that sold the Albariño wine with brand and label.
