Brežice (; ) is a town in eastern Slovenia in the Lower Sava Valley, near the Croatian border. It is the seat of the Municipality of Brežice. It lies in the center of the Brežice Plain (), which is part of the larger Krka Flat (). The area was traditionally divided between Lower Styria (territory on the left bank of the Sava River) and Lower Carniola (territory on the right bank of the Sava River). The entire municipality is now included in the Lower Sava Statistical Region. Brežice prides itself on a rich historical and cultural heritage. The Lower Sava Valley Museum (), housed in Brežice Castle, contains archaeological and ethnological exhibits, exhibits on the Croatian and Slovenian peasant revolt, and a modern history collection. It is one of the largest regional museums in the country. A more recent landmark addition to the town is its water tower, as well as the double arches of the 527 m long iron bridge, which spans the Sava and Krka rivers. History Celtic graves from the 2nd century BC have been discovered in Brežice, and it has been continuously settled since prehistoric times. A Slavic settlement called Gradišče was established at the site soon after the arrival of the Slovenes in the area. The castle in Brežice was first mentioned in 1249. The current structure dates to 1529. Brežice was affected by Ottoman raids several times during the 15th and 16th centuries. Peasant uprisings took place during the 16th century; in 1515 peasants attacked the castle in Brežice, burned it, and killed the nobility sheltering in it. The new castle was able to withstand the peasant uprising of 1573. The first school was established in Brežice in 1668, taught by Franciscan friars at the friary. From 1774 to 1780 instruction took place at Baron Moscon's residence, and from 1780 to 1820 at the rectory. A separate school building was built in 1875. A general hospital was established in Brežice in 1872. Its facilities were expanded in 1889. During the Second World War, Brežice and the adjacent countryside to the north and west were known as the Rann Triangle (), an area intended for the resettlement of Gottschee Germans that had been evicted from the Gottschee region in the territory annexed by Italy. Brežice expanded after the Second World War by annexing the neighboring villages of Brezina (), Črnč (), Šentlenart (), Trnje (),
