The half-excavated bullring Curiosity · Endrinal, Guijuelo, Salamanca Image of Endrinal, not of the place itself. Beside the hermitage of El Mensegal a bullring half cut into the ground is preserved; the existence of a bull-pen ring in this same place is documented as early as the fifteenth century, and amateur bullfights are still held in it during the festivals.
