Pink House Museum, Government museum in Plaza de Mayo, Buenos Aires, Argentina.

The Museo de la Casa Rosada occupies the former Taylor Customs House galleries beside the Casa Rosada, a 5,000-square-metre space of exposed red-brick arches and piers forming a long corridor with a pale grey floor. Fourteen bays framed by the old customs arches hold screens and period objects; some ceilings and walls are glass.

The museum occupies the former galleries of the Aduana de Taylor, the customs house of Buenos Aires, and opened on 24 May 2011 under President Cristina Kirchner. It was renamed Museo Casa Rosada under Mauricio Macri, reverted to Museo del Bicentenario under Alberto Fernández in 2020, and took the name Museo de la Casa Rosada under Javier Milei in early 2024. It serves as an annex of the Casa Rosada.

The museum's name has shifted with each government: opened in 2011 as Museo del Bicentenario, renamed Museo Casa Rosada under Macri, reverted by Alberto Fernández in 2020, then changed back to Museo de la Casa Rosada in early 2024. Its centrepiece is Ejercicio plástico, painted in 1933 by David Alfaro Siqueiros with Lino Enea Spilimbergo, Antonio Berni, Juan Carlos Castagnino and Enrique Lázaro, declared a national historic-artistic asset in 2003.

The museum occupies the old Taylor Customs House galleries behind the Casa Rosada, entered from Plaza Colón side; its 5,000 square metres are organised as fourteen brick-arched chambers along a single timeline route, so follow the arches in order. The Siqueiros mural and the archaeological remains of the Fuerte de Buenos Aires are inside the same circuit. A confitería and a gift shop are on site.

The museum occupies the former galleries of the Aduana de Taylor, the customs house begun in the 1850s, and its brick arches still divide the exhibition into fourteen chambers. Finds from excavations of the Fuerte de Buenos Aires are displayed, and the 1933 mural Ejercicio plástico by David Alfaro Siqueiros hangs here, declared a national historic-artistic asset in 2003.
