Coi has the remarkable Rizzardini house, an imposing building in a village consisting mainly of rustic buildings; one of the frescoes on its exterior dates back to 1713. Along the road from Coi to Maresòn the two Rizzardini mills, existing prior to 1634, were still working in 1946. The Piva mill is also interesting with its large wooden wheel and was active from 1948 until the 70s.
Brusadaz has the old Costa mill, perhaps amongst those mentioned in a document of 1693. Outside the village are the remains of the San Pellegrino mine and especially the old Da Dòf mine whose entrance is still visible.
From the relaxing and welcoming village of Costa is possible to reach one of the most ancient Val di Zoldo haylofts (tabià): the Mas di Sabe, which dates back to the XVI Century.
