Castrelos Park, also known as Finca de la Marquesa or Quiñones de León Municipal Park, is a large park located in Vigo.

The park occupies a total area of 24 hectares, where the Pazo de Castrelos and its historic gardens, a wide variety of green spaces, an auditorium, wooded areas, etc. are located. All fully harmonized as an urban park, it has a great landscape and botanical value, which is why it was declared a Historic Garden and Asset of Cultural Interest in 1955.

At present, it is the largest park in the city, a rest area and a true green lung of the great city.

The pazo represents the baroque splendor of palatial architecture. It was built in the second half of the seventeenth century and is currently one of the best examples of Galician palace architecture.

The park has its origin in the gardens of the pazo. Which was originally a tower known as Torre de Lavandeira.

In the 15th century from the fortress the raids of the pirates that harassed the Ría de Vigo were fought.

It also served as a defense in the war that Castile declares against Portugal, causing the rupture of the old Kingdom of Galicia. The tower is abandoned after the withdrawal of the Portuguese army between 1665 and 1670.

The pazo belonged between 1678 and 1918 to the Gago de Mendoza Oca Sarmiento y Montenegro family, from Antonio Feliz Tavarés Ozores y Soutomayor to Fernando Quiñones de León y Elduayen, Marquis of Valladares and Mos. And the Marquesa de Valladares, with her marriage to Fernando Quiñones de León, is the one who expands the house and arranges the gardens with an English taste.

The last Marquis of Alcedo donated the pazo with the fifth of it to the city council and the town of Vigo in 1924 for the transformation of the pazo into a national art museum and the fifth into a municipal park.
