Image and Memory: Argentina 1976–2003. Photographs by Eduardo Longoni

Preview: written before the show opened

Eduardo Longoni, born in Buenos Aires in 1959, started as a photographer at the Noticias Argentinas agency in 1979, in the middle of the military dictatorship. He worked the street: his pictures from those years include the first marches of the Madres de Plaza de Mayo, and they have since been shown in more than 50 countries.

This show marks 50 years since the 1976 coup and runs on to 2003, through citizen resistance, police violence and the slow return of democratic freedoms. You see it in the cloister on the first floor, as part of the permanent-collection route. The museum calls it the start of a new line of work on Latin America's recent history, a turn for a collection better known for Inca gold and colonial casta paintings.

It's covered by the €3 museum ticket, free on Sundays and on Thursdays from 14:00. The museum closes at 15:00 on most days.
