After the accident of 1963, in which the whole place was buried, this church was built, which is architecturally worth seeing. You can “climb onto the roof” of the church from the outside and from there you have a good view of the Piave valley.

Longarone Town Hall

Highlight • Monument

The Alpine town 100 kilometres from Venice, set between jagged needle peaks, is a memorial to human resilience. It is beautiful again, rebuilt, set in the long valley of the Piave River facing the mountain that brought disaster.
