Nebet Tepe, Fortress and hill in Plovdiv, Bulgaria

Nebet Tepe is a flat, grassy plateau on one of Plovdiv's hills, edged by low walls of rough grey and brown stone blocks. Near the centre stands a short, thick curved remnant of uneven blocks and rubble, with plants at its base; the wall continues along the plateau edge behind it. Dark graffiti, including the letters "BDF", marks a block in the left wall, and red-roofed houses of the town lie beyond.

The fortress began around 4000 BC and was later enlarged and rebuilt by Thracians, Macedonians, and Romans in turn. Each civilization left its mark through new construction and reworking of earlier structures.

The name comes from Turkish words 'nevbet' meaning watch and 'tepe' meaning hill, reflecting the site's role as a lookout point in older times. This term remains alive in local speech and the city's memory today.

The climb to the top is manageable on foot, and the location offers views of the city from above. It helps to wear good shoes since the paths are uneven and you can move freely among the ruins.

A hidden underground passage with a staircase from the 6th century connects the citadel to the Maritsa river below. This secret route allowed residents to reach water quickly or escape if needed.
