Memorial en Recordación de los Detenidos Desaparecidos, War memorial in Vaz Ferreira Park, Montevideo, Uruguay.

The Memorial en Recordación de los Detenidos Desaparecidos stands in Carlos Vaz Ferreira Park on the southern slope of Montevideo's Cerro. Its central section consists of two glass walls inscribed with 174 names, set on a geometric concrete structure that leaves the natural rock visible at the side. It was declared a National Historic Monument in 2014.

The memorial originated from a proposal by Senator Manuel Singlet to Montevideo mayor Mariano Arana. In June 1998 the city council approved the project, and a national competition drew 42 entries; the winning design was by architects Martha Kohen and Ruben Otero with artist Mario Sagradini. Construction began in August 2001 and the memorial was inaugurated on 10 December 2001, Human Rights Day. It was declared a National Historic Monument in 2014.

The engraved names on the glass panels create a direct confrontation with individual stories of loss, inviting visitors to pause and reflect on each person commemorated. The site serves as a gathering place where families and community members return to honor those who were taken.

The memorial sits within the open Vaz Ferreira Park and remains free and accessible year-round without time restrictions. Visiting during daylight hours works best, as this allows you to read the names clearly and see the river backdrop through the glass.

The 1998 competition drew 42 entries; the winning team was architect Martha Kohen, architect Ruben Otero and visual artist Mario Sagradini, with agronomist Rafael Dodera and Diego López de Haro and Pablo Frontini. The concrete structure leaves the natural rock of the Cerro's southern slope visible at its side. The memorial won first prize at the 2002 Quito Pan-American Architecture Biennial and a silver medal at the first Miami Art Biennial.
