The official name of the Colo Colo stadium is "Monumental David Arellano" but the neighbourhood is
called "Pedreros" so the stadium is commonly known as "Monumental" or "Pedreros". Catolica plays most of the matches in the San Carlos de Apoquindo stadium (20.000, build in 1988) but all big derbies are played in the national stadium of Chile.
