The Panathenaic Stadium, also known as the Kallimarmaro is the venue where the first Olympic Games of the modern era took place back in 1896.
The cache is a magnetic container hidden in front of the Stadium.
Bring your own pen.
Suggestion: It is worthy to visit this cache at night in order to admire the "Kallimarmaro" stadium with the artificial light!
The FTF goes to Brevetoskylo!
