STRIUMTI. – An ancient Benedictine abbey in the Casentino, founded by Teugrimo or Teudegrimo, of the Guidi family, towards the end of the 10th century.
Dedicated to St Fedele, its origins may perhaps be traced to the renewed flourishing of the cult of this saint (cf. Anal. Bolland., 9 [1890], pp. 354–59, and 21 [1902], p. 29 ff.; BHL, 2925); yet by the mid-11th century it was already in decline, so much so that around 1085 the Benedictines were succeeded by the Vallombrosans (certainly dependent on the latter in 1090, as is evident from a privilege of Urban II: Jaffé-Wattenbach, 5433), whose first abbot was the Blessed Andrea da Parma. Shortly after the mid-12th century GIOVANNI B (v.), who later became antipope under the name of Callisto III. Towards the end of the same century, under Abbot Placido, the continual strife between Guelphs and Ghibellines made the site untenable, and the monks began to move to Poppi, which was fortified by the Guidi.
The new abbey, likewise dedicated to St Fedele, enjoyed a flourishing existence until the 15th century, while Strumi, abandoned, dwindled to a ruin (the church still stood in 1583, but no longer in 1630).
The abbey of Poppi was granted in commendam to the archbishops of Florence during the 15th century, but in 1510 Julius II restored it to the Vallombrosans. Suppressed in 1809 under the Napoleonic laws, it was never reconstituted: the church of S. Fedele still remains, with some fine paintings and a 13th-century Tuscan school panel depicting a Madonna.
