The Museum of Pontevedra is a museum that aims to offer art exhibitions of all kinds and especially the art of Galicia, for the artistic and cultural development of the province. It was founded by the Provincial Council of Pontevedra in December 1927 and began as a support to the action of the Archaeological Society of Pontevedra, installing its headquarters in the pazo of Castro Monteagudo.

It consists of five buildings for exhibitions: the Ruins of Santo Domingo and the García Flórez, Fernández López, Sarmiento and Castro Monteagudo buildings, with another under construction.

The Castro Monteagudo building was built in 1760 by José de Castro y Monteagudo, who was the first auditor of the maritime province of Pontevedra. In its rooms you can find archaeological pieces, gold and silverware from the pre-Roman and Roman periods, silverware and paintings. Two rooms are dedicated to archaeological themes in which prehistoric remains can be found, including various necklaces and other Roman pieces from the Golada and Caldas sites. Special mention should be made of the collection of silverware donated by Gonzalo Fernández de la Mora y Mon, which is a collection of works from before 1900 with a majority of civil art pieces as opposed to sacred art. The oldest work is a Byzantine bowl from the 15th or 16th century, but perhaps the most valuable is an imperial tureen forged in Strasbourg in 1800.

The García Flórez building is an 18th century house that has been used as a museum since 1943, housing navigators' apparatus and furniture, religious sculptures and jet pieces. The first floor is mostly dedicated to Castelao.

The * Fernández López building*, built between 1962 and 1965, houses the painting collection, with a collection of Romantic and historical paintings and a room dedicated to Francisco de Goya and another to Joaquín Sorolla. It also houses the museum's administrative offices and library. It also houses the graphic archive consisting of half a million images, together with the Zagala archive with photographs donated by the photographer Francisco Zagala, as well as the archives of the photographers José Suárez and Joaquín Pintos.

The ruinas de Santo Domingo are the oldest building in the museum, and belonged to the convent of the same name, although only the porticoed chevet remains. This building was requested by the Archaeological Society, but it was not available until 1947. The main chapel and the side chapels can be seen in the vicinity, together with the remains of the church and a collection of coats of arms, tombstones, baldachins, capitals and various statues.
The library has an extensive collection and the museum publishes a magazine entitled "El Museo de Pontevedra desde 1942" (The Museum of Pontevedra since 1942).
