This village's name had its origin at the Couto de Avão, since there was no bridge on the Alva river and the Moura brook and one could only enter the old town "a vau" (ad vadum). The poet-warrior Brás Garcia Mascarenhas, author of the epic poem Viriato (18th century) once lived here. These lands were inhabited by the romans, perhaps the founders of the now ruined castle. Among the monuments, a special note to the mother church, whose construction may have been ordered by Dom Afonso Henriques, a 16th century manor, a pillory and a chapel.

From the former Roman city the round arch still exists. It is settled in strong pillars and has several tombstones and other traces.

Castle located on the Bank of the river Alva, with a wall with 3.50 metres high by 2.70 meters wide. It was built in the 13th century and rebuilt in the 14th century. By the door is the chapel of St Michael, with a ship with protruding chancel and two vaulted side niches.

Its pre – romanic origin makes this church a rare example in Portugal. This Mozarabs temple reflects the diversity of influences that affected the first Reconquest period. The singularity of this church comes from the reused materials, Roman, Visigoth and Arabs, from the porch monumentality and from the three naves with horseshoe arches.

A park with abundant vegetation, the town's "lung". There is an amphitheatre, a fitness circuit, a lake with a waterfall, a school orchard, a playground and a picnic area.

Sunny building with carved stonework Windows and small curved cutting apron possessing high headboard, clipped, with a coat of Faria and Garces and another of Macedos.

Set of Neolithic graves.

This manor house was built in the XVI century and it went under remodelling work on the XVIII century. The chapel has to be mentioned; with it gallery and lateral entrance through the rectangular door finishing in triangular pediment, as well as the images and the golden carve.

In this temple, which was the aim of many reforms through the centuries, it is worth to mention the lateral chapel from the 14th century, the Manueline main chapel with cruised arch decorated and the carving from the 17th and 18th centuries.
