Abbey of Santa Maria in Sylvis

After the fall of the Lombard Kingdom in 774 and the subsequent rebellion of Friuli in 776, the abbey had all its properties confirmed by Charlemagne through a chart including total exemption from any tax obligation to lay authorities.

From 1441 to 1786, the abbey was a commandry; its first lay abbot was cardinal Pietro Barbo, later Pope Paul II; in the following centuries he was succeeded in general by members of noble families from the Republic of Venice.

At the side of the tower is a Renaissance portal with a round arch supported by pillars, dating from the Michiel and Grimani restorations.

West of the bell tower is the Palazzo della Cancelleria ("Chancellor's Palace"), built in brickwork in the 12th–13th centuries, with a height of 9 m (30 ft).

At the center of the crypt is the Urn of St. Anastasia, formed by a single marble block of Greek origin; it was realized by Cividale masters in the 8th century, and has decorations with flowers, crosses, arches, tondoes and rose motifs.
