Jesenice (, ) is a Slovenian town and the seat of the Municipality of Jesenice on the southern side of the Karawanks, bordering Austria to the north. Jesenice is known as the Slovenian home of mining and iron making industries, its largest steel company Acroni, and its ice hockey club, HK Acroni Jesenice. Historically, Jesenice's ironworks and metallurgy industries were the driving force of the town's development. History Name Jesenice was attested in written sources in 1337 as villa de Jesenicza (and as Assnigkh and Asnigkh in 1381, and Jasnickh and Aisnstnick in 1493–1501). The name is derived from *Jesen(ьn)icě, a locative singular form of Jesenik (< *Esenьnikъ). The suffix -ě became -i in the local dialect and was reinterpreted as a nominative masculine plural, the accusative of which (in -e) was subsequently reinterpreted as today's feminine nominative plural. The name is derived from the common noun *jesenik 'ash woods' (< jesen 'ash tree'), thus originally meaning 'in the ash woods' and referring to the local vegetation. The modern German name of the town is Aßling. Middle Ages Jesenice was first mentioned as Assling in a 1004 deed of donation issued by King Henry II of Germany, in which nearby Bled (Veldes at the time) was also mentioned. There were no settlements there at that time, and the name Assling only marked an area on the banks of Jesenica Creek. Later, a settlement slowly started to grow around the area now known as Murova, where St. Leonard's Church is today. With the March of Carniola it passed to the Austrian House of Habsburg upon the Battle on the Marchfeld in 1278. There are few sources for the early history of Jesenice; most of them focus on ironworks. The oldest is a set of mining rights issued to the Carinthian counts of Ortenburg, dating to 1381. According to the document, the first settlements in the area (like Planina pod Golico) were founded on the southern slopes of the Karawanks due to need for wood, flowing water for mills, and iron ore. With the development of new techniques of extraction of iron from ore, the need for water energy grew, and the small streams on the slopes of the Karawanks were no longer sufficient. The ore-extracting industry was thus relocated to the valley in 1538, when Bernardo Bucellini from Bergamo gained permission from the Habsburg King Ferdinand I to move the ironworks
