Mausoleum of Néstor Kirchner, Modern mausoleum in Río Gallegos, Argentina.

The Mausoleum of Néstor Kirchner is a rectangular structure in Río Gallegos, 13 meters long, 15 meters wide and 11 meters tall. Its front facade is clad in tan and beige stone tiles in a staggered pattern, with four tall dark vertical slits and three shorter horizontal openings on the left. The left side is smooth light grey concrete, and the building sits on a lawn behind a black iron fence with pointed finials.

Néstor Kirchner died in 2010 and received a state funeral; the mausoleum was built the following year, 2011, by Lázaro Báez. It holds his remains and those of his parents, his mother Ana María Ostoic having died in 2013. In 2013 part of the structure gave way, damaging the floor and some walls, reportedly because of the building's weight on low ground.

Inside, a Racing Club football shirt, a rosary, a flower and the white headscarves of the Mothers and Grandmothers of Plaza de Mayo rest on the coffin, which lies under an Argentine flag behind a tall wooden cross. Outside, a giant flagpole flies the Argentine flag beside two votive flames, a fountain and a triangular form representing the country's territory.

The mausoleum stands on low ground in Río Gallegos, Santa Cruz, and in 2013 part of the structure settled, damaging the floor and some walls. The complex covers 65 square metres, with a giant flagpole, two votive flames, a triangular monument and a fountain outside. Inside, a wooden door opens onto a spiral staircase to the first floor, where a circular glass opening looks down on the coffin.

The mausoleum was built by Lázaro Báez, the businessman later linked to corruption cases involving the Kirchner governments. Inside, behind the coffin, stands a large wooden cross, and the coffin is draped with an Argentine flag.
