Tlos is an ancient ruined Lycian hilltop citadel in the Antalya Province of southern Turkey, was rediscovered by Charles Fellows in 1838. Tlos is believed to be one of the most important religious Lycian cites and settlement on the site is said to begin more than 4, 000 years ago. The influence of many cultures upon Tlos has resulted in a patchwork of structures dominated by an acropolis and fortress. On the slopes leading up to the acropolis are numerous Lycian sarcophagi and many house- and temple-type tombs cut into the face of the hill. One such is the Tomb of Bellerophon, a large temple-type tomb with an unfinished facade of four columns featuring a relief in its porch of the legendary hero Bellerophon riding his winged horse Pegasus. A carving of a lion or leopard is inside the tomb. At the foot of the hill is a Roman stadium with seating capacity for 2, 500 people.
