Zappeion Mansion

Built in Athens in 1874, this mansion with its Corinthian columns and neoclassic style, was used in the Olympic Games in 1896 for fencing events and then again in 2004 for the press centre. It was the first building to be erected specifically for the revival of the Olympic Games in the modern world...so says Wikipedia ! It has a wonderful location beside the National Gardens (free entry btw) and the Temple of the Olympian Zeus, which is a tad older, built in 2AD !
