Šentjernej (in Slovenian pronounced as /ʃɛnˈtjɛːɾnɛi̯/ or in Slovenian pronounced as /ʃənˈtjɛːɾnɛi̯/; in older sources also Šent Jernej,[2] German: Sankt Bartlmä[2]) is a small town in southeastern Slovenia. It is the seat of the Municipality of Šentjernej. It lies in the center of the Šentjernej Plain (Slovenian: Šentjernejsko polje), which is part of the larger Krka Flat (Slovenian: Krška ravan). The area is part of the traditional region of Lower Carniola. It is now included in the Southeast Slovenia Statistical Region.[3]
The parish church, from which the town also gets its name, is dedicated to Saint Bartholomew (Slovenian: sveti Jernej) and belongs to the Roman Catholic Diocese of Novo Mesto. It is a Baroque building with remains of two earlier churches, one Romanesque from the 12th century and the other a 15th-century Gothic one, preserved in the floor of the current building. Two 18th-century side altars were brought to the church from the Cistercian monastery at Kostanjevica.[4]
