Today, the archaeological complex on the hill is one of the most popular tourist sights in Plovdiv and a cultural monument of national significance.

The remains of city walls, towers and ancient buildings were found during the excavations on Nebet Tepe.

The oldest part of the walls on the hill dating from the 4th c. BC was built with large syenite blocks closely fitted together with minimal clearance between adjacent stones and no use of mortar, typical for ancient cyclopean masonry.

One of the most interesting excavations is the unique postern with staircase from Roman times: a secret tunnel in the rocks under the North wall built in the 6th century AD during the reign of Justinian.

A large rectangular water reservoir with a volume of 350 m3 is preserved in the Southern part of Nebet Tepe.
