3 km from Mariazell in the south, on the Sigmundsberg, lies the chapel of the same name.
It was built in 1443, fortified with a circular wall in 1464 and destroyed in 1485 by mercenaries of King Mathias Corvinus.
In 1501 it was rebuilt and in 1827, after the terrible fire catastrophe, it housed the statue of the Virgin until the basilica was rebuilt.
St. Sebastian's Church was designed by the master builder of the Mariazell Basilica - Domenico Sciassia - and built from 1644. The central building on a cruciform ground plan is the last stop for pilgrims on the "via sacra" from Vienna to Mariazell.
The martyrdom of the church patron is impressively depicted on the column in front of the high altar. Parts of the high altar were created by MichaelHönel in 1643 and were originally intended for an altar in the basilica. Around 1730 the altar was changed and placed in St. Sebastian.
The altar piece "Assumption of Mary" is by Fridericus Stilpp, above it are the coronation of Mary and statues of St. John the Evangelist and St. John the Baptist. On the side are the sculptures of St. Lambert as the patron saint of St. Lambrecht Abbey and St. Benedict.
