Trnovo (pronounced as /sl/ or pronounced as /sl/; Italian: Tarnova della Selva) is a village in western Slovenia in the Municipality of Nova Gorica. It is located on the high Trnovo Forest Plateau (Slovenian: Trnovski gozd) in the traditional Slovene Littoral region.[2]
Trnovo is the site of a mass grave from the period immediately after the Second World War. The Zalesnika Shaft Mass Grave (Slovenian: Grobišče Brezno Zalesnika), also known as the Wild Apple Shaft Mass Grave (Slovenian: Grobišče Brezno za lesniko), is located 1.5km (00.9miles) northeast of the village on the right side of the road to Lokve. It contains the remains of Home Guard and Italian prisoners of war and Slovene civilians murdered in May 1945.[3]
The parish church in the settlement is dedicated to Our Lady of the Snows and belongs to the Diocese of Koper.[4]
