Galgenberg, Natural monument in Wullersdorf, Austria.

Galgenberg is a natural monument in the Weinviertel region that rises to 346 meters and is surrounded by gently rolling hills. Agricultural fields and vineyards cover the terrain, with a network of marked walking paths crossing through the landscape.

Oberstinkenbrunn belonged to the Carthusian monastery of Gaming from 1338 to 1782. In 1346 the monastery received high jurisdiction, making the village its own court district. The surviving gallows column, about 6 meters high and built of stone and mostly brick, was repaired after 2001, when fallen bricks were rebuilt into a pyramidal top.

The gallows column appears in Oberstinkenbrunn's coat of arms, and the site's grim reputation kept people away for centuries. That avoidance, plus the need to keep a high court visible, left the summit open as pasture since the Neolithic. Today sheep graze the dry grassland in rotation to hold back shrubs.

The gallows column and the dry grassland lie on the summit plateau, reached on foot from Oberstinkenbrunn; no road leads up. The core area belongs to the Naturschutzbund and is grazed by sheep in rotating paddocks, so keep to the edges and leave the fenced plots closed. The shallow, skeletal soil over marl and limestone gets muddy after rain.

The surviving gallows column is about 6 metres high, square in plan and built mostly of brick on stone. Its asymmetrical footprint suggests a second column once stood beside it, joined by wooden beams; no trace of another column remains. After 2001 fallen bricks were rebuilt into a pyramidal tip.
