Edificio de la antigua Aduana de Bilbao, Eclectic architecture building in Bilbao, Spain.

The former customs house of Bilbao, designed by Eladio Iturría in 1890, stands on the Uribitarte promenade next to Pío Baroja square and the Aznar building, facing the city hall. Its main facades, overlooking Barroeta Aldamar street and Pío Baroja square, mix neoclassical and herreriano elements in an eclectic style. The building has a ground floor and two upper floors.

Built in 1890 to a design by Eladio Iturría, the building handled goods arriving by ship at the port of Bilbao. Renovation works began on 22 June 2014 to house state administration services for Bizkaia, and the building reopened on 2 November 2020 after the opening was postponed from 1 July 2020 due to the coronavirus pandemic.

The building's name recalls its role collecting customs duties on goods unloaded from ships at the Uribitarte quays. Its eclectic facades mix neoclassical and herreriano elements, facing Barroeta Aldamar street and Pío Baroja square. Since 2020 it has housed public services such as the Provincial Traffic Headquarters and the Foreigners' Office.

The building is easily reached from the Uribitarte waterfront path and surrounding squares, making it straightforward to locate and view. Its position along the water provides a natural gathering point and clear visual reference when exploring the riverside area.

The building's official opening was set for 1 July 2020 but was postponed to autumn because of the coronavirus pandemic; it finally opened on 2 November 2020. Its ground floor houses the Provincial Traffic Headquarters and the Foreigners' Office, while the upper floors hold Demarcación de Costas, Muface, Fogasa and the Territorial Directorate of Commerce.
