Museo Mitre, Historical house museum in San Martin Street, Buenos Aires, Argentina.
Museo Mitre is a residential house with Spanish colonial architecture on San Martin Street, featuring multiple open courtyards that connect to each other. The building preserves rooms as they were during Mitre's time, with a central well located in the second courtyard.
Built in 1785 for Marcelino Carranza, the house sheltered the deposed viceroy Baltasar Hidalgo de Cisneros after the May Revolution of 1810. Bartolomé Mitre rented it in 1860 and lived there until his death in 1906; in 1868 a citizens' committee bought it and gave it to him. On 9 July 1860 Mitre, Urquiza and Derqui met in this house.
The museum holds Mitre's personal library on the upper floor, with over 20,000 volumes in 22 categories covering American history, geography and languages from the 16th to the early 20th century. The American Library sits within a general collection of more than 70,000 volumes, alongside an archive of over 48,000 manuscript pieces.
The museum sits in the financial district and is easy to reach by public transport or on foot. Visitors should note that opening hours are limited to afternoon times, and the interior consists of multiple connected rooms that can be explored at a leisurely pace.
The house's facade appeared on the reverse of Argentina's 2-peso banknotes, which remained legal tender until 30 April 2018. The La Nación newspaper was founded here by Mitre in 1870 and moved in 1895 to a building on the adjoining northern plot, designed by his son Emilio Mitre and later demolished for the Torre San Martín 344.
