The Vizcaya Regional Government building is fundamental to the contemporary architecture of the Basque Country.

This building was inaugurated in 1900 and it is the work of Luis Alarden. It is compact and elegant, and is one of the most best examples of Eclecticism. The large windows on the façade stand out especially, along with the grand balcony over the main entrance. It is sumptuously decorated, in response to the need that the bourgeoisie of the time felt to express their economic power.

The interior of the palace is outstanding for its large staircase and decor, with plenty of marble, wood, stucco, mirrors, plasterwork, vases, ceramics, windows and paintings by important artists from the end of the 19th century.
