Moissac is very famous of it's abbey, the late-romanesque church, and specially the monastery with it's beautiful ambulatory are real gems in French architecture.
The church from inside, then from outside:

The monastery with it's wonderful ambulatory.

On our way from Moissac to Albi we visited Bruniquel, an interesting castel in the valley of Aveyron. The castle is in bad repair, but not a ruin, there are exhibitions and performances held in the buildings.

From Bruniquel we passed the same afternoon on to Cordes-sur-Ciel.
The little village seems to be left here from more hundred years ago.
