A municipality annexed to the Vall de Boí since 1965. This is the village which best represents the idiosyncrasy of this valley, both thanks to the preservation of the Romanesque elements in the church of La Nativitat and the hermitage of Sant Quirc, as well as the urban structure of the village, which has maintained the appearance of a livestock breeding village.
Durro is considered to be the town that best represents the personality of the Vall de Boí area, both for the preservation of the Romanesque features in its Nativitat Church and the shrine of Saint Quirc, and for its structure, which maintains the look of a livestock farming town.
This is reflected in a group of buildings that includes stepped houses, wider roads than other medieval towns in the area, and more separated buildings. These have very varied exterior decoration: large balconies with side beams, some with balcony windows, and the typical bare stone construction with very steep slate roofs.
Many old farm houses of great interest are preserved, many of which have been converted into rural tourism accommodation: Garbot House, Marqués House and Xoquin House, for example. It was an independent municipality until 1965, when it was annexed to Vall de Boí.
