Myndos, one of the Carian cities, is located within the borders of the province of Muğla, district of Bodrum, township of Gümüşlük today. Situated just across the ancient city, Asar / Tavşan Island is in a very important location to safeguard the city’s port. Some of the building remnants unearthed as a result of the research on the island are dated to the Classical Period and later. The clearing at the entrance of Asar Island and some architectural finds support the idea that there was a propylon(?) at the entrance. In addition, a stylobate, which is thought to belong to the “U” / “Π” formed altar structure, was found on the upper terraces of the island. Thanks to the excavations conducted in that area, an inscription, which was understood to be dedicated to Apollon Archegetes, points out the existence of a cult area belonging to Apollon on the island. Within the scope of the study, some architectural suggestions were presented about possible structures by comparing the altar and propylon (?) structures with similar examples.
