In 1902 Grases won a national design competition for the Monument to Alfonso XII of Spain to be erected in the Buen Retiro Park. His design was a grand and elaborate curved colonnade, topped with a bronze equestrian statue of the king by sculptor Mariano Benlliure, and incorporating the work of 21 other artists. The monument was inaugurated on 3 July 1922, after Grases' death.
