The castle of Serravalle is a complex of ruins at the mouth of the Blenio valley.
On this rock spur, the first fortifications were built in 900, but they were destroyed and rebuilt over time.

This mandatory extra loop will take you to the stunning Blenio-Valley - also called "Valle del Sole". We will send you sightseeing at the remains of Castello di Serravalle. A short but very impressive section to slow down and push / carry your bike through the ruins of the ancient castle. The parcours is mandatory but can be ridden in direction of your choice!

Situated on an enchanting hill in an elevated position, it probably belonged, as its name testifies, to a castle destroyed in 1518 by the Uranians. It is an enchanting building with two parallel naves, built at two different times. The primitive chapel, perhaps aristocratic, with a round apse and a single two-storey nave (the lower probably a crypt) survived the demolition of the castle. The plan of the current church does not correspond to the primitive one, but is the result of an addition to the north of another nave, completed with a square chancel from the early fifteenth century.
