The Hill of Saint Leonard (dosso di San Leonardo in Italian) is a striking porphyritic rock spur on the northern side of the valley.
It can be reached through a road which starts in Lisignago, town a bit to the south of Cembra.
In the past, at the top of the hill it stood the Castle of Lisignago: actually from there it was possible to dominate the whole surrounding area. The fortress was knocked down in the 13th century in consequence of a popular rebellion: the community of Cembra had later to pay as an indemnity 100 pounds of Veronese denari to Adalpreto of Mezzo (currently the town of Mezzocorona) and Grolando of Salorno.
At the summit of the hill there is now a little church embellished by 15th century frescoes. Noteworthy a big Last supper and, by the right side altar, Saint Leonard and Saint Helen with the cross: the frescoes are attributed to the same artist who painted the walls of the church of Saint Mary in Cembra.
Unfortunately the plaster of other frescoes has fallen and there have emerged, fascinating anyway, the sinopites (the preparatory drawings done with clay of Sinope before spreading the plaster): Saint Leonard, the Trinity, the Madonna of the Mercy and Saint Ursula carrying the flag with a cross.
If staying by the little church, you pause to behold the Avisio and its valley you'll realize that the great sight that you can enjoy from the hill would be worthy alone of the journey to go to the top.
