In the beginning, it was known as Plaza del Azogue and was designed as a meeting place and a market for the daily sale of foodstuffs.

[5] In 1809, the central 18th century house located to the west of the square (at number 8) served as headquarters for the occupying French troops.

[8] On 2 June 1858, the Liceo Casino moved to the Pazo of the Counts of San Román and remained there until the inauguration of its own building on 2 August 1878.

The square has six stone benches and twelve orange trees lined up symmetrically on its north and south sides.

[13][14] On the north side of the square is the Pazo de los Gago y Montenegro, from the 16th century, with a Gothic arch in the door and five Voussoirs.

It refers to the occupation of the Gago family as guardians of the gate of the walls of Pontevedra in the tower of the Burgo Bridge.

[17] On the east side, on the edge of Calle Real, is the Pazo of the Marquis of Aranda (mayor of the Kingdom of Galicia) from the beginning of the 18th century, with a crenellated tower (at the beginning it had two crenellated towers at its ends) and a coat of arms on its large facade with the only figures of two holders on each side in a coat of arms of the city.

Classics of Galician literature were printed there, such as the first edition of Os vellos non-deben de namorarse by Castelao, in 1953.
