Greece. It was built in 1895 as Neo Phaliron Velodrome, to host the cycling events for the 1896 Summer Olympics in Athens, and the pitch was covered with curm. Olympiacos started using it since its foundation in 1925. In 1964, the stadium was renovated and was given its current name after Georgios Karaiskakis, a military commander of the Greek War of Independence, with an athletics track around the pitch. Olympiacos left the Karaiskakis Stadium temporarily to play home matches at the newly built Athens Olympic Stadium in 1984. After a five-year use (1984–1989) of the biggest stadium in Greece, the team returned to their traditional home, where they played until 1997. It was then that Olympiacos got back to the Athens Olympic Stadium, where they stayed for another period of five years (1997–2002). In 2002, the Olympic Stadium was closed for renovation works due to the 2004 Summer Olympics and Olympiacos moved to the Georgios Kamaras Stadium in Rizoupoli, home of Apollon Smyrnis, for the following two seasons (2002–2004). Meanwhile, the Karaiskakis Stadium had fallen in disrepair and was not anymore suitable for football matches. In 2003, its use passed to Olympiacos in order to build a football-only ground, to be used for the football tournament of the 2004 Olympics. In return, Olympiacos got exclusive use of the stadium until 2052, covering all maintenance costs and also paying 15% of revenue to the Greek State. The old stadium was demolished in the spring of 2003 and the new one was completed on 30 June 2004 at a total cost of €60 million. Nowadays, the Karaiskakis Stadium is one of the most modern football grounds in Europe, also hosting the museum of Olympiacos, with several facilities around.
