The monks of Admont built this church in a grandiose setting in the 15C, to perpetuate their devotion to a relic of the Holy Blood (Heilig Blut) which is said to have been brought here in the 10C by Briccius, an officer of Byzantium's Imperial Court, now lying in the crypt. The Gothic chancel and nave are both covered with network and star vaulting. Outstanding furnishings include the high-altar's great altarpiece and a pale-sandstone Gothic canopy.
