Tolmin is situated on the southern rim of the Julian Alps, the largest settlement in the Upper So?a Valley (Slovene: Zgornje Poso?je), close to the border with Italy. It is located on a terrace above the confluence of the So?a and Tolminka rivers, positioned beneath steep mountainous valleys. The old town gave its name to the entire Tolmin area (Slovene: Tolminsko) as its economic, cultural and administrative centre.
The area is located in the historic Gori?ka region, itself part of the larger Slovene Littoral, about 41 km (25 mi) north of Nova Gorica and 87 km (54 mi) west of the Slovene capital Ljubljana. In the north, the road leads further up the So?a River to Bovec, with an eastern branch-off to ?kofja Loka and Idrija.
Early inhabitants were Illyrians in Tolmin area. It was ruled successively by the Roman Empire, Odoacer, the Ostrogoths, the Eastern Roman Empire and part of the Lombard Duchy of Friuli until it was conquered by the Frankish king Charlemagne in 774 and replaced by the Carolingian March of Friuli.
Ancestors of Slovenes had come to this area during the Slavic settlement of the Eastern Alps from about 600 onwards, embattled by Avar raids. It was passed to Middle Francia in 843 after the Treaty of Verdun and in 952 passed to the vast March of Verona, which was initially ruled by the Dukes of Bavaria, from 976 by the Carinthian dukes. King Henry IV of Germany ceded it to the newly established Patria del Friuli in 1077, before it was occupied by the Republic of Venice in 1420. Finally the Tolmin area was conquered by the Habsburg Emperor Maximilian I during the War of the League of Cambrai in 1509.
Tolmin was then ruled with the possessions of the extinct Counts of Gorizia as part of the Inner Austrian territories of the Habsburg Monarchy. In 1713 it was the centre of a peasant revolt against increased taxation and the local Count Coronini. It was part of the Illyrian Provinces, which were part of Napoleonic French Empire between 1809 and 1814 before returning to Austrian rule. Until 1918, the town (under bilingual names Tolmein - Tolmin) was part of the Austro-Hungarian monarchy (Austrian side after the compromise of 1867) and head of the district of the same name, one of the 11 Bezirkshauptmannschaften in the Austrian Littoral province. A post-office was opened in October 1850 under the German name (only).
After World War I it was ruled by the Kingdom of Italy between 1918 and 1943 (nominally to 1947). It was a county (comune) center in Province of Gorizia between 1918 and 1923 and again between 1927 and 1943 (nominally to 1947) and in Province of Friuli between 1923 and 1927 during Italian rule as Tolmino. After the Italian caputilation, it was occupied by Nazi Germany in 1943 and was part of Operational Zone of the Adriatic Littoral before liberation by Yugoslav partisans. After temporary division of Julian March by Morgan Line, Tolmin was part of Zone-B, which was under Yugoslav administrators. It was officially passed from Italy to Yugoslavia in 1947 after the Treaty of Paris. Finally Tolmin was passed to Slovenia after breakup of Yugoslavia in 1991.
The area is home to a multitude of vestiges from World War I. The most significant relic of the time is the Javorca Church, dedicated to the Holy Spirit built above the Polog shepherds outpost in the Tolminka Valley by Austro-Hungarian soldiers to commemorate their deceased comrades.
The museum, library, schools, and the town's open spaces provide venues for a variety of events, exhibitions, and presentations all year round. The Tolmin region is also a popular destination for artists from Slovenia and abroad.
Tolmin is known for the "Metalcamp" festival since 2004, which since 2013 is called Metaldays, which every year attracts about 10,000 people from whole Europe and other parts of world. Other festivals held in Tolmin are Punk Rock Holiday and the Overjam reggae festival.
