Tiglieto Abbey, founded in 1120, was the first Cistercian abbey to be founded in Italy, and also the first outside France. It was a daughter house of La Ferté Abbey. The first abbot was probably Opizzone. It may have gained the name Tiglieto after being given the estate of that name by the Margrave Anselm of Ponsone in 1131.
In 1442, through Pope Eugenius IV, Tiglieto became an abbey in commendam. In 1648 it was turned into a family estate of the last commendatory abbot, Cardinal Raggio, and dissolved. In 1747 the area was occupied by the Austrians, who shortly afterwards were driven out by the Genoese. In 2000 Tiglieto was reoccupied by the Cistercians.
The church is a primitive Romanesque brick basilica; the original side-chapels were removed in the 14th century to make way for a new east end. The nave was vaulted in the Baroque period, and a new choir at the west end was added at the same time, as was a Baroque campanile.
The conventual buildings are to the south of the church. The early Gothic chapter house in the east range has survived, with a square chapter room with nine bays from the early 13th century and symmetrical triforium windows looking onto the central courtyard and the site of the cloister, no longer extant, with the dormitory with bricked-up windows in the upper storey, as have the sacristy, the Fraternei and to the south the refectory building, as well as the lay brothers' block in the west, now converted for residential purposes.
The entire precinct was renovated for the new community that took over the premises in 2000.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
