The necropolis located on the slopes of the acropolis hill was used continuously from the Classical period and onwards. The rock-cut tombs constitute the most important group among the burial types attested at the necropolis. These tombs are notable particularly in terms of their ostentatious façades imitating traditional wooden architecture of Lycia. In some of the tombs, instead of just carving, architectural elements were added to the decoration. In addition, there are monumental rock-cut tombs with façades depicting the fronts of temples. Although the interiors of tombs have different features, most include stone beds for the placement of the dead. The offerings and the bones of the previous burials were swept into the pits dugout into the center of the rock-cut tombs. It is also clear that the interior of these tombs, which were sometimes used as family tombs, were often altered in the subsequent periods. In particular, the stone beds were placed by the ones built of bricks in the Roman times. The second major group of burial type in the necropolis of Tlos is composed of the sarcophagi. These sarcophagi can be sub-divided into two groups in terms of their designs. The first group is the Lycian type sarcophagi characterized by lids topped by ogival roofs, while the second group of sarcophagi of Roman date is characterized by triangular roofs. The sarcophagi often rest upon a hyposorion were the dependents were held, although there are cases in which they were placed on podiums. In addition, numerous chamber tombs and chamosorion-type burials are to be attested on the steep slopes of the acropolis hill.
