It was built by María de los Dolores Elduayen y Martínez Enríquez, IX Marquise of Valladares and VII Marquise of Mos in the Pazo de Castrelos.

Because the English daughter-in-law of the Marquise Mariana de Whyte was very fond of this game, in which other friends and relatives soon began to take up.

The stands and posts are still preserved on the estate, although due to the danger of falling trees and branches, access to the public is closed on certain days.
