Provincial Museum Complex «Enrique Udaondo», Museum complex in Luján, Argentina

The Provincial Museum Complex Enrique Udaondo occupies three and a half blocks in Luján, about 65 km from Buenos Aires. It comprises the Museo Colonial e Histórico in the former Cabildo and Casa del Virrey, the Museo de Transportes, and the Salón del Automóvil. New pavilions reproduce colonial buildings such as the Aduana Vieja and the convent of the Monjas de Santa Catalina, and the gardens hold a replica of a colonial chapel.

By decree 1362 bis of 31 December 1917, provincial commissioner José Luis Cantilo assigned the old Luján cabildo and the Casa del Virrey, the former royal tobacco and playing-card monopoly, as the seat of a colonial and historical museum, with engineer Martín Noel restoring the buildings. It opened on 12 October 1923 under honorary director Enrique Udaondo. Both buildings were declared National Historic Monuments on 21 May 1942.

The museum's rooms trace the colonial era, the British invasions, the May Revolution and the independence struggles. The gaucho room is named after Ricardo Güiraldes, author of Don Segundo Sombra, and displays criollo art. The upper floor preserves the chapter house of the old cabildo.

The museum is located about 65 kilometers from Buenos Aires and is best reached by public transport or car. Guided tours are offered in multiple languages, and reduced admission rates apply for students and seniors.

The transport section also holds the quinchada cart "El Plumerillo" and the sopanda, a type of litter used by General Manuel Belgrano. These pieces sit beside La Porteña, Argentina's first locomotive, and are easy to walk past.
