Aduana de Iquique, Historical customs building in Iquique, Chile.

The Aduana de Iquique, also called Palacio Rímac, is a colonial-classical building on the city's historic block, now the seat of the Museo Naval de Iquique. Its two-storey rectangular body is topped by an octagonal watchtower over the entrance, and inside are courtyards ringed by covered corridors.

The structure was constructed in 1871 following an order by Peruvian President Jose Balta to replace an earlier building destroyed in the 1868 tsunami. Its establishment marked the region's recovery and reinforcement of maritime trade infrastructure after the disaster.

The building blends colonial and neoclassical design, with Oregon pine beams visible in its northern and eastern warehouse sections. Visitors can observe these architectural details and the craftsmanship in the courtyards and interior corridors.

The building is accessible to visitors and contains a museum with historical exhibits that provide insight into local maritime heritage. The interior courtyards and corridors allow visitors to explore the architecture and layout at a comfortable pace.

The building hosted the body of frigate captain Arturo Prat Chacón after his death, and in 1879 it served as a prison for 49 Chilean survivors of the Naval Battle of Iquique. In 1891 it was the scene of the Combat of the Aduana de Iquique.
