The Calderón Theatre is the main theater of the city. This theater is named after Calderón de la Barca, an important Spanish poet and playwright. It is located in the center of the city a few meters from other significant monuments such as the Cathedral, the church of Nuestra Señora de las Angustias or the church of Santa María La Antigua. Every year it hosts the Valladolid International Film Week (SEMINCI). In the space in which the theater is located today, the palace of the Admiral of Castile was built until the mid-XIX century and was completely demolished to build the current theater. The Theater was inaugurated on September 28, 1864 with the representation of El alcalde de Zalamea of Callderón de la Barca.
It currently has a capacity for 1,141 people and hosts during the season performances of theater, opera, zarzuela, dance, ballet, flamenco and jazz.
