Irje is a settlement on the southern slopes of Mount Boč in the Municipality of Rogaška Slatina in eastern Slovenia. The entire area of Rogaška Slatina traditionally belonged to the Styria region and is now included in the Savinja statistical region.
Širje (pronounced [ˈʃiːɾjɛ]) is a settlement in the Municipality of Laško in eastern Slovenia. It lies on the left bank of the Sava River, immediately northwest of Zidani Most. The area was traditionally part of the Styria region. It is now included with the rest of the municipality in the Savinja Statistical Region.
The name of the settlement was changed from Marija-Širje (literally, 'Our Lady of Širje') to Širje in 1955. The name was changed on the basis of the 1948 Law on Names of Settlements and Designations of Squares, Streets, and Buildings as part of efforts by Slovenia’s postwar communist government to remove religious elements from toponyms.
The parish church, known as Marija Širje, is dedicated to the Immaculate Conception and belongs to the Roman Catholic Diocese of Celje. It was originally a Romanesque building that was extended in 1747 and partially rebuilt in 1873.
