The site of Gloska Cuka is situated on a small hill on the left bank of the Vardar River, 4.5 km south of the village of Grciste, Valandovo. In 1977, the Museum of Macedonia conducted rescue excavations on the Iron Age necropolis, but systematic excavations at the settlement began in 2006.
On the Eastern Terrace, remains of the prehistoric settlement have been discovered. A house built in the prehistoric manner was partially unearthed. In the house a fireplace and a large number of hand mills for wheat were discovered, along with many pottery fragments and other movable finds that date the house to the 7th-6th century BC. In the southern room, a cyst grave with a child burial was discovered. A part of a house with trenches for the wall foundations and postholes carved in the bedrock belongs to the earlier stratum. The movable finds (coarse hand-made vessels and kantharoi) date the house to the 9th-8th century BC.
The researches on the Acropolis have shown that a small fortified settlement existed here during the 2nd and 1st centuries BC. At the SE edge, a part of a building with storage rooms with pithoi and a stone platform for a hand mill for wheat was discovered, and in the SW part of the Acropolis parts of buildings with several building phases were discovered, as well as part of a rampart and a small tower, which dates to the very end of the settlement life, more precisely, towards the end of the 1st century BC. In these buildings, there was an abundance of movable finds: bronze coins from the autonomous mints of Pella, Amphipolis, Thessalonica and the Macedonian kings Philip V and Perseus, silver republican denarii, various types of Hellenistic vessels, terracotta figurines, tools and weapons.
