Moorish architecture is evident in many cities in Spain. But Neo-Mudéjar – a form of Moorish Revival – is rare in Barcelona, a notable exception being the Arc de Triomf. Casa de las Alturas was built in 1890 as the residence for the director of the General Society of Water. Since 1989, it has been the Municipal Council’s headquarters for Horta-Guinardó, one of Barcelona’s ten districts.
