Arriaga theatre is in Bilbo, next to the Arenal square. Its architect was Joaquin Ruboda. He made the theatre in memory of Juan Crisostomo Arriaga, because Arriaga was a musician but he died when he was young. The theatre was finished in 1890.
Arriaga has got different pictures in its front, for example musical instruments and mask, and it is easy to recognise it as a theatre.
