Museo Juan Galo Lavalle, Historical museum in San Salvador de Jujuy, Argentina

Museo Juan Galo Lavalle occupies a mid-18th-century mansion at Lavalle 252, with nine rooms and two internal patios. Its rooms display sculptures, paintings, furniture, documents, banners, firearms, swords, and civil and military clothing. A temporary exhibition room and a video and conference room complete the layout.

The house was built in the mid-18th century and was declared a National Historic Monument in 1941, on the centenary of Lavalle's death. On 9 October 1841 federal troops reached the building and fired at the door; a bullet pierced the lock and mortally wounded General Juan Galo Lavalle, who died later that day at 44. The museum opened in 1943 and moved to this site at Lavalle 252 in 1962.

The museum bears Lavalle's name because federal troops shot him through the door lock here on 9 October 1841, at age 44. Rooms also hold the quepis caps worn by officers of the 12th National Guard squadron, kept as among the collection's most emblematic objects, alongside trophies from the Battle of Suipacha.

The museum is at Lavalle 252 in the city centre, in the old mansion where Lavalle died. Its nine rooms and two inner patios are arranged without a chronological order, so follow the sequence of the colonial, independence, Jujuy Exodus and governors rooms to make sense of the collection. A temporary exhibition room and a video and conference room complete the visit.

The bullet that killed Lavalle passed through the lock of the door, and the house keeps 9 rooms and 2 inner patios rather than the three courtyards sometimes described. Look for the quepis caps of the 12th National Guard squadron, kept in the Independence room.
