It is more or less certain that the significant historical remains on the hill dominating the bay of Türkbükü on the northwest side of the Bodrum Peninsula and Aşağı Göl Köyü at the shore of it are the remains of Lelegian town Madnasa. Friedrich Cornelius who did not have knowledge of this fact thought that Madnasa, whose name took place in the lists showing the amount of talanton paid by each town as an expense contribution to the Delian Confederacy read on the inscriptions found in Attika, was the Maeander Magnesia. Moreover he mistakenly stated that it is the same town as Maddunassa which took place in Hittite documentation and which was on the route of Tudhalia the Second on his war journey to Arzawa. However it is absolutely impossible that Lelegian Madnasa on the Bodrum Peninsula was Maddunassa because Bodrum Peninsula is nowhere to be stopped at from the country of Hittites to Arzawa countries; it is by the sea at the edge of mainland.

It looks like the name Madnassa had been created from the elements Ma-(u)dna-(a)ssa of the Luwi language. It means it is the town of Ma country.

We have little information about the history of Madnasa town entioned in the works of Ancient Plinius and Byzantion Stephanos. From the Attika inscriptions mentioned above, we find out that this town paid 2 talantons (silver equivalent to 600 Atatürk golds) at first, then 1 talanton to the Delian Confederacy in the leadership of Athens in 5th century BC as an expense contribution. However this situation did not prevent it to be forced to "join" to Alikarnassos/Bodrum, in other words its people obliged to get transferred to Bodrum in the era of Mausolos; therefore history of Madnasa as an accommodated town ended towards the end of the first half of the 4th century BC (around 360 BC).

To reach the remains at the bay, make a left to well-paved route that reaches to the villages on the northwest at the crossroads where Bodrum-Milas road passes through the Bodrum Peninsula and approaches to the north shore. You can even take this road to Yalıkavak. Climbing to the area of the remains is easier from the ridges of Lower Gölköy across the northeast slopes and takes about 40 minutes.

The summit where the Madnasa Acropolis is located is 2 km away from the Lower Gölköy in cove's fly. People of the area call this summit Kalkayığı Hill.
