Thanks to the prosperity the city underwent during the 14th century, Avignon became one of the main Gothic architecture ensembles in Europe. Nowadays Avignon definitely is The Gothic town in Europe.
In the photo you can see the Popes Palace; the most beautiful and strongest mansion in the world according to Froissart. The building was edified in two parts. The first part, more sober, was erected by Benoit XII between 1334 and 1342. The second part was built between 1342 and 1352 by Clément VI.
Currently the building hosts a museum and an exhibitions hall. The entrance to these halls is not cheap, but it is well worth the money. One of the most interesting features of the Palace is the great collections of frescoes. Painters from all Europe, most of them from Sienna, came to Avignon to decorate its main rooms.
