Celentino and Strombiano are two hamlets of the municipality of Pejo at 1,260 m a.s.l. and have about 100 inhabitants each.

In Strombiano you should visit Casa Grazioli, also known as "Casa de la Béga", an ancient farmer's house where the original and entirely preserved rooms of such houses can be visited: the stüa fodrara (bedroom), the fornela ole (an old ceramic stove), the old kitchens with a so-called fogolár (fireplace) and the bread ovens. This house is a pillar of the Ecomuseo "Piccolo Mondo Alpino" in the Val di Peio.

From Strombiano it is approximately an hour's walk to the Museo della Malga (1,980 m a.s.l.) above the village, where you can discover all the items and tools used until not so many years ago.
