The Mariazell Basilica is a Marian basilica in Mariazell, Austria. It is the most important pilgrimage destination in Austria and one of the most visited shrines in Europe. In the church, a miraculous wooden image of the Virgin Mary is honored.
The territory around Mariazell was given to the Monastery of St. Lambrecht around 1103, and the monks built cells there in order to serve the local residents. Legends give the town's founding day as December 21, 1157, but it is first documented in 1243. A Marian altar was dedicated there in 1266.
