One is the Archaeological sites of exceptional importance Iustiniana Prima,[1] a 6th-century Byzantine city built by the emperor Justinian I, and the other is Svinjarička Čuka locality, a Neolithic settlement, discovered in 2017–2018.

The village rests on the western slopes of the Kremen mountain [fr], which here divides the regions of Pusta Reka and Jablanica.

[1] Today, the village of Štulac constitutes a local community (mesna zajednica), a sub-municipal administrative unit, within the municipality of Lebane.

[1] In 2017 the archaeological "Pusta Reka Project" started, focusing on the beginning of the Neolithic in the Leskovac Basin.

In the top layers an accumulation of pottery and other artifacts from the Late Iron Age were discovered, dated to the first half of the first millennium BC.

Important individual finds include three trapezoid-shaped, almost complete chalices and an anthropomorphic clay figurine, with arms in a position of adoration.

Based on the shapes and ornaments of the vessels, it is estimated that the settlement belongs to the younger or classical Starčevo phase, at the moment tentatively dated to the first half of the 6th millennium BC.

[7][10] However, palaeogeographic drillings from 2017 showed a cultural layer below the depth of 2 m (6 ft 7 in), centuries older than the one excavated in 2018 and dated before 6000 BC.

[7] Excavations were continued in August–September 2019, investigating these deeper layers and new terrain on the river terrace the site is situated on.
