A short distance from Salardú, elevated further to the N, at an altitude of 1,280 m, is the small town of Unha (114 inhabitants), at the foot of Pui de Unha, dominated by the SE Unhòla river shortly before its confluence with the river Garonne. At its entrance coming from Salardú, we find one of the most interesting civil buildings in the Valley, Ço de Brastet, an old manor house built in 1580, fortified, with Renaissance windows and portal.

At the other end of the nucleus is the parish church of Santa Eulalia, a Romanesque building (12th century), with an irregular floor plan and small dimensions, divided into three unequal naves for circular pillars that support semicircular arches, from where the vaults of the cover.

The octagonal bell tower with a square base dates from 1775 and its roof has a peculiar bulb-shaped finish, with an oriental air.
