Mount Pentadaktylos lies just across the "Green Line" from the Greek capital of Nicosia, and is an iconic part of the city's skyline. So in the 1980s, a group of patriotic Turks used white stones to mark out a giant version of the Northern Cyprus flag on the side of the mountain. The flag covers about 50 acres of the slope, the size of four football stadiums. If you want to see the giant flag up close and personal, it's a two-hour bike ride from the border to the village of Kaynakköy, and then a 40-minute hike up the hillside.
