Monaco

The Stade Louis II is the compact home of AS Monaco, located at 7 avenue des Castelans in the Fontvieille district of the Principality of Monaco. The stadium holds 18,523 spectators and was inaugurated in January 1985, replacing the earlier Stade Louis I that had served the club since 1939. Named after Prince Louis II of Monaco, a patron of sport in the principality, the ground is built partially into the cliff face of Monaco's Rock and sits beside the harbour and the Mediterranean Sea, giving it one of the most unique settings of any professional football venue in the world. The stadium is partly subterranean, with its upper tiers at street level while the playing surface and lower stands are below ground.

AS Monaco have a distinguished history in French and European football, having won eight Ligue 1 titles and reached the UEFA Champions League final in 2004, losing 3-0 to Porto. That Monaco squad, assembled on a budget that dwarfed the competition, included Didier Drogba, Fernando Morientes, Ludovic Giuly, and was managed by Didier Deschamps. Earlier, Monaco won their first title in 1961 under Lucien Leduc, and Arsene Wenger managed the club from 1987 to 1994, winning the championship in 1988 with Glenn Hoddle and Mark Hateley in the squad. The principality's unique status as a tax-free territory has attracted wealthy players and investors throughout the club's history.

The Stade Louis II's unusual below-ground construction means its atmosphere is unusually contained and loud for a relatively small venue, with the stands close to the pitch and the enclosed setting amplifying noise significantly. The stadium is one of European football's most remarkable ground-sharing venues, as Stade Louis II also hosts the UEFA Super Cup when Monaco host it. Recent investment from Russian billionaire Dmitry Rybolovlev transformed the club in the 2010s, leading to the celebrated 2016-17 Ligue 1 title and Champions League semi-final run. A new larger stadium has been discussed to better serve Monaco's European ambitions, though the principality's unique geographic constraints make expansion exceptionally challenging.
