The Estádio das Antas was the third (and longest occupied) stadium of the Portuguese football side FC Porto. It was in use from 1952 to 2004, replacing the earlier Campo da Constituição, 1.6km (1 mile) to the west, and later replaced by the Estádio do Dragão, a block southeast away. As well as the stadium, it had an indoor arena and three training grounds. Wikipedia
