The first defensive structures date back to the period between the XIII and the XII centuries. BC: they are structures with more orders of palisades, wooden gabions (filled with debris rock and soil) and with a embankment (bank "C") to defend small residential and craft buildings (metallurgical activity, production of ceramics, etc.). It is the castle of the Bronze Age that will be destroyed by a large fire probably caused by a war.
Between the IX and the VIII century before Christ the castle of Noàl is rebuilt even more powerful raising more the embankment to have monumental dimensions visible from far away. To counteract the thrust of the embankment towards the interior, buttresses are built against which there are small residential and artiginal buildings. In the V-IV century B.C. (presence of the ancient Venetians) the embankment is further raised. Even in the Iron Age an extensive series of fires caused by war events will cause its destruction.
The first high fortified wooden structure of historical age (a tower) should date back to the Goths (VI century). It is however later that the first important defensive work consists of tower in boulders tied with mortar and embankment consisting of palificate and pebbles. This is the first complex to be called "castle" (said of the Mirabèi, Mirabello). It consisted of a tower, a fortified enclosure and housing and craft buildings arranged around a rainwater basin (puddle). Its final destruction, by the joint militias of Belluno and Feltre led by Bishop Gerardo de Taccoli, occurred in 1196 during the wars that see the latter opposed to the Municipality of Treviso that had occupied it.
The archaeological route. To relive the history of Noàl, inside the Park there is an educational path equipped with panels that illustrate the history of the place, the research, the findings and signal the layers of the different eras of the castle/ castle.
At the top of the tower, built with a height similar to that of the ancient and to protect the remains, with a panoramic view of the valley and the peaks of the Park of the Belluno Dolomites, there is instead the classroom, equipped with display cases that hold perfect copies of the finds, illustrative panels and panoramic panels to view and identify the ancient network of castles, protohistoric settlements, watchtowers, the main peaks of the mountains around, the villages, the Piave and the Cordevole.
Hiking (comfortable footwear is recommended).
1) In Landris, about 1 km north of Sedico, when the Agordina regional road starts to climb towards Roe Alte, a large sign indicates the beginning of the path that in about half an hour walk, between path and secondary road, leads to the park of Noàl.
2) Just north of Sedico, before the roundabout, a road sign indicates the beginning of Via Mirabèi and the route to Park Noàl, which is about twenty minutes away. Joining the two paths, you can make an interesting loop.
