Greece is home to several ancient and modern stadiums, reflecting its rich history in sports, particularly in the context of the Olympic Games. The most famous is the Panathenaic Stadium in Athens, which was originally built in 330 BC and renovated for the first modern Olympics in 1896. It is unique for being constructed entirely of marble. Another notable stadium is the Karaiskakis Stadium in Piraeus, primarily used for football. Opened in 2004, it serves as the home ground for the Olympiacos F.C. and has hosted various international matches, including the UEFA Champions League. These stadiums highlight Greece's ongoing passion for sports.
