Pantheon of the Patriarchs of Lisbon, Pantheon in São Vicente, Lisbon, Portugal

The Pantheon of the Patriarchs is a rectangular room in the Monastery of São Vicente de Fora, built only in the 20th century. It has no azulejos and holds a plain stone altar; a cross stands at one end and the entrance is on one of the long sides. It was previously the monastery's chapter house, tiled and fitted with choir stalls for the Augustinian canons.

The room was the chapter house of the Canons Regular of Saint Augustine at São Vicente de Fora, tiled and fitted with choir stalls. After the monasteries were dissolved it stored Portuguese Army papers, then stood empty. The Estado Novo ceded it to the Patriarchate of Lisbon; works finished in 1954 and the remains were moved there in late 1955.

The room was the chapter house of the Canons Regular of Saint Augustine, who met in choir stalls beneath azulejo tiles; those tiles are gone, leaving a bare rectangular hall with a plain stone altar and a cross at one end. Since late 1955 it has held the tombs of most Cardinal-Patriarchs of Lisbon, from Carlos da Cunha e Meneses (1759–1825) to José da Cruz Policarpo (1936–2014).

The pantheon is a rectangular room inside the Monastery of São Vicente de Fora, entered through a door on one of its long sides; a cross marks one end. It has no azulejo tiles, only a plain stone altar, so the tombs are the main thing to look at. The monastery stands in the São Vicente parish of Lisbon, in the Alfama area.

The room was the monastery's chapter house, tiled and fitted with choir stalls for the Augustinian canons, before becoming an army paper depot. The future Cardinal-Patriarch Manuel Gonçalves Cerejeira (1888–1977) is among those re-interred here in late 1955.
