Dedicated to St. Ulrich, it has a very ancient history and was mentioned for the first time in a papal bull by Pope Callixtus II in 1123, followed by another bull written by Pope Innocent II in 1135. It was rebuilt in the 18th century (the last consecration dates back to 1746) using part of the building's previous wall, and it was erected on the embankment of the roman street Claudia Augusta, near the place where, according to the tradition, the saints Theonistus, Tabra and Tabratha were martyred.
It is interesting to notice how the church's orientation has been changed: the old church's façade faced southwards, towards the Sile river, whereas the new entrance is rotated 90 degrees and overlooks Musestre.
