The Estádio da Madeira, better known as the Choupana, houses Nacional. The current stadium is located around nearby training pitches. The club also built an academy campus in name of its most famous player, Real Madrid's Cristiano Ronaldo. The stadium was renovated in 2007 for a new stand and also increasing the capacity to over 5,000 spectators. The total price of the renovations was €20 million.
In these new facilities, no stands were put behind the goals, with a tall fence used in its place. In mid-2007, the stadium name was changed to Estádio da Madeira, because of the excellent sports facilities.
Nacional has a big rivalry with Madeira-neighbours Club Sport Marítimo. Historically, Marítimo dominated Nacional in the early years, being the first to reach European competition. Nacional, however, have crept up in the UEFA standings, finishing fourth twice and fifth in the 2000s.
The Madeira Derby is often associated with the clubs' followers differing culture and way of life. The fans of Nacional, being of a higher socio-economic status than those of Marítimo, were mainly lobbyists for the commercial expansion of Madeira, but the working class Marítimo followers were keen to preserve Madeira. This only exacerbated the ill-feeling between the clubs.
The rivalry heightened when youngster Ronaldo declined an offer from Marítimo in favour of Nacional, where his godfather was a member of the board. Politics plays a part in both the Madeira and the Azores derbies, because of Madeira's controversial regional governor, Alberto João Jardim, being a self-confessed Marítimo supporter. Jardim does not have a good relationship with Carlos César, the regional governor of the Azores, and an avid C.D. Santa Clara fan.
