Opening of the National Stadium

The National Stadium Sports Complex (Portuguese: Complexo Desportivo do Estádio Nacional/Complexo Desportivo do Jamor), also known as Jamor Sports Complex, is a national football ground used by the Portugal national team and, as of 2018, by Belenenses SAD. It is located in the civil parish of Algés, Linda-a-Velha e Cruz Quebrada-Dafundo, in the municipality of Oeiras, in the western part of Lisbon District.

The stadium entered UEFA history as host of the first ever game played in UEFA club competitions. The game was played on 4 September 1955 between Primeira Divisão's third-placed team, Sporting CP, and Yugoslav champions, Serbian side Partizan Belgrade. It ended as a 3–3 draw and was the first game to be played of the first edition of the European Cup.
