A term cross and a source-laundry dated in century XVIII give the welcome to the population.

It is a town practically left, whose earths are cultivated by the old inhabitants from their new establishments.

The urban layout is of great simplicity owing to his reduced size and the low number of inhabitants who lived there. The urban layout is reduced to the way to access there and a cross-sectional street to this way. Also there is a square that connects with this main street and completes the layout.

The village, although it presents an aspect neglected as a result of the abandonment, is very interested by its homogeneity and the original state that constructions present.

At the entrance of the town there is a sheltered under arch source which is made of ashlar masonery. It is completed with a drinking trough and a laundry. It can be a construction of the century XVIII.
