Paslı was a Roman town on the eastern slope of the Yenibahce valley (turkish Yenibahce Deresi) above the holiday resort Atakent. The ancient name of the small town is not known.

On an area of about 150 × 200 meters are distributed about 40 houses, which are apparently distributed in an unorderly manner. The oldest houses can be dated to Late Hellenistic times. They were built of polygonal blocks with bosses.

The youngest houses are built in polygonal masonry and large blocks and date from the Roman imperial period. The small cuboid work typical of the early Byzantine period does not appear, even though crosses can be seen on some lintels.

A Late Hellenistic wall running from west to east divides the place into two sections. It is double-skinned with a filling of stone and clay and has a 1.30 metre wide door. Their purpose is not clear. The greater part of the settlement is south of it. At the eastern end of the wall follows another one running south, which is not exactly timed because of its otherwise unknown technique. It is based on small limestones, on top of which are smooth, partly polygonal cuboids. At least since Late Antiquity, the two walls have protected the place. A tomb of the imperial era is incorporated into the north-south wall in the manner of a projecting tower.

Some houses usually have bell-shaped cisterns that were carved directly out of the rock.
