"The Vall de Boi is a narrow valley, carved deep into the Catalan Pyrenees. More than 1,000 years ago, seven small villages emerged in the valley, which no one would remember if nine Romanesque churches hadn't been built at that time. The isolation has contributed to the fact that at least some of these churches have been preserved almost in their original state," says the website for the television series "Treasures of the World - Heritage of Humanity." Comprising several hundred episodes, the series (in German) presents special places from all continents and eras that – despite all their diversity – have one thing in common: They have been awarded the honorary title of World Heritage Site by UNESCO. The film about the VALL DE BOI with its Romanesque churches is available in the ARD media library under the following link => https://www.ardmediathek.de/video/schaetze-der-welt/vall-de-boi-spanien-folge-260/swr/Y3JpZDovL3N3ci5kZS82ODk4NDYw

The Romanesque church of Sant Feliu de Barruera dates from the 11th century, although the nave, the bell tower, two chapels and the portal were added in the 12th century. It is very interesting to compare the different architectural details according to the period in which they were built.

Consecrated on December 10, 1123 by Ramon Guillem, Bishop of Roda-Barbastro, the church of Sant Climent de Taüll is built on top of an 11th century temple. It is the prototype of a Romanesque church with a basilica plan with three naves separated by columns and a gabled wooden roof, a head with three apses and a bell tower. The image of Christ in Majesty by Taüll has been one of the emblematic images most used to represent the Catalan Romanesque

Of the Romanesque churches in the Vall de Boí, this is one of the most beautiful. The original frescoes are in the museum, as always. Here they are digitally reconstructed and projected onto the walls. In addition, there is a very interesting digital reconstruction of the original artwork.

A very pretty suspension bridge that crosses the Noguera de Tor river. You may even notice it moving around a bit, which can be exciting for some and scary for others.

This port connects the Noguera Ribagorzana river basin with the Sis valley and the Isábena basin, right on the border between Catalonia and Aragon. From Bonansa, the pass is a little over six kilometers long, with a fairly constant average drop of around 7%. Its other slope, the one that follows the Obarra gorge until it crowns the port, is much longer. It is 15 kilometers long, but it is very flat, with percentages around 3%, until it practically reaches the top, where the last two kilometers present considerable unevenness, with ramps of more than 15%.

The port of Bonansa is located at an altitude of 1,380 meters, in an open area from which you can see the panorama of the surrounding mountains. The climb is demanding, but worth it.
