The Pazo de Mugartegui, or Pazo de los Condes de Fefiñáns, is a baroque pazo dating from the 18th century. It currently houses the headquarters of the Regulatory Council of the Rías Baixas Denomination of Origin.

It is located in the Plaza de la Pedreira, in the heart of the old city of Pontevedra, very close to the medieval Puente del Burgo. The large amount of stones accumulated in front of the pazo of Mugartegui for the construction of the pazo, as well as the Church of San Bartolomé and the school of the Society of Jesus, led to this space being called Plaza de la Pedreira.

The pazo was built for José Manuel Valladares y Figueroa, Count of Fefiñáns, on the ruins of a 17th century house. It was the work of the master mason Pedro Antonio Herrero, who completed the construction in 1771 (with the exception of the coat of arms), which was finished in 1773. The pazo belonged to the Fernández de Mugártegui family, related to the Valladares family, from whom it bears its present name.

During the 19th century, the mansion became an educational centre, as it housed the Normal School for male teachers. In the 20th century, it was divided into several rooms and, in the 1950s, it was the headquarters of the Academia de Estudios Jovellanos.

Today, it belongs to the Pontevedra City Council, which bought it on 20 November 1998 and commissioned the architect Jesús Aser Fole to renovate it. The headquarters of the Control Board of the Rías Bajas wine appellation of origin has been installed in the premises since 2003, with a wine museum on the ground floor, while its rooms are used by the City Council for protocol, cultural and social events.45 The pazo was opened for these new functions on 24 March 2001.

The building has a façade with an arched entrance. The ground floor has arches that gave access to the former stables and cellars and to the staff quarters, with seven arches supported by small columns of the Tuscan order.Above these arcades, the first floor has seven French windows. Opposite the central French window, there is a small balcony with an iron railing.

The central body is surrounded by pilasters crowned with pinnacles. At the top, there is a frontispiece in the semi-circular pediment, from which are sculpted rococo coats of arms and, above, a sundial and a stone sun, whose rays emanate from a face with smiling cheeks. The coat of arms shows the arms of the Figueroa, Arango, Quirós and Omaña lines.

At the back, the terrace that used to open out as a viewpoint over the Lérez river stands out.
