Žiče Charterhouse, Gothic monastery ruins in Slovenske Konjice Municipality, Slovenia.

Žiče Charterhouse is a former Carthusian monastery in the valley of Žičnica Creek near Žiče, in the Municipality of Slovenske Konjice. Its surviving Gothic complex includes the single-nave church of St. John the Baptist, two cloisters, monk cells, a chapter house, refectory, kitchen and prior's house. The upper monastery's walled precinct follows a nearly triangular plan adapted to the terrain.

Founded in 1165, the monastery operated as a Carthusian community for nearly four centuries until Turkish invasions and economic difficulties caused its decline. The site was gradually abandoned as broader changes affected the region and religious institutions faced new challenges.

The name Žiče derives from the Slovene word for hare, zajec, after the legend that a frightened hare jumped into Ottokar III's lap. The monastery was long called Seiz Charterhouse in German, and its coat of arms bears an initial S. Lay brothers at Špitalič ran a hospice offering alms, clothing, food and medicines made from herbs grown on site.

The grounds are typically accessible for visitors to explore the ruins and layout at their own pace without requiring tickets. Sturdy footwear is helpful since the terrain is uneven and the site spreads across different levels.

The monastery's name comes from a legend: after a white hind led Ottokar III to the site, a frightened rabbit jumped into his lap and he shouted "Zajec, glej no, zajec!" ("A rabbit, look, a rabbit!"). The German form Seiz, from zajec, gave the house its long-used name Seiz Charterhouse, and the initial S appears on the left side of its 1730 coat of arms.
