Vrabinec Castle, Medieval castle ruin in Babětín, Czech Republic.

Vrabinec Castle is a ruin on a basalt hill at 400 metres above the right bank of the Elbe, rising over Těchlovice in the Ústí nad Labem region. Only fragments of the perimeter walls remain, built around a courtyard between three jagged basalt rocks; a round bastion guarded the entrance and a residential tower stood on the highest rock.

Archaeology shows occupation in the 13th century, but the first written record is from 1403, when Ješek of Těchlovice held the castle. Zikmund Děčínský of Vartenberk bought it in 1415 without living there; Mikuláš of Lobkovice held it in 1425, Anežka of Šternberk two years later. The army of the Lusatian Six Cities probably took it in 1444; it was still a seigneurial centre in 1504 but deserted by 1515.

The castle's name, Vrabinec, means "sparrow place" in Czech, and its German name Sperlingstein carries the same image. The hilltop rocks and the surrounding slope are part of the Vrabinec nature reserve within the České středohoří protected landscape area, so the ruin is visited together with the protected basalt slope.

The ruin stands on a basalt hill at 400 m above the village of Těchlovice, on the right bank of the Elbe. The hill and its summit rocks lie within the Vrabinec nature reserve and the České středohoří protected landscape area. Only remnants of the perimeter walls survive, so the site is best visited on foot via marked trails.

Archaeological research found the remains of two gates with shafts for the counterweights of drawbridges, a detail easy to miss among the surviving perimeter walls. The castle stood on three split basalt rocks at 400 metres, with the courtyard between them and a round bastion guarding the entrance.
