Generally speaking, the older and more seemingly disorganized a cathedral, the more interesting we find it. Saint-Sauveur in Aix is hard to beat in that regard. We have seen older cathedral renovations: e.g.,  a baroque church built on top of a 
Greek Doric temple in Sicily. But Saint-Sauveur was built on top of the Roman forum, incorporating bits of it, first as a parish church, then revised as the church of one of the orders, then finally revised as a cathedral when Aix became the capital. It's always fascinating to see the layers of Romanesque, Gothic, then Baroque, side by side or one on top of the other. Add a conspicuous layer of Roman, or Greek, and you really have something.

| Facade of the cathedral complex |

| Guess who attended the university across the street | 
|  | 
| Gothic facade | 
|  | 
| Helpful floor-plan; looks like a conventional nave with two side aisles; but it's more complicated than that, with the aisles (and chapels) having come in in
 different ages and for different purposes...
 | 
|  | 
| It's all fascinating, but the Baptistry is the most fascinating: eight Roman columns with Corinthian capitals, recycled from the Forum; we'll see this octagonal baptistry
 design again in Frejus, a few miles down the road

|  | 
| Gothic nave/aisle | 
|  | 
| Interesting non-Christian-looking pediment up high in the Romanesque nave
 | 
|  | 
| Few windows | 
|  | 
| So visits to the cloisters are by guided tour only, so we interrupt this visit to the cathedral to have a look into the Romanesque cloisters
 | 
|  | 
| Thus nicely landscaped | 
|  | 
| The carving quite good, old, generally well-preserved | 
|  | 
| "Please proceed to the left" | 
|  | 
| The capitals in the four corners are the attributes of the four gospel writers; here, my personal favorite, the lion, Mark
 | 
|  | 
| Highly regarded statue of St. Peter | 
|  | 
| Now in the Baptistry, looking up at the dome and oculus, much later additions | 
|  | 
| Original baptistry pool, the oldest bit, going back to early Christian times | 
|  | 
| Remnant of painting in Baptistry | 
|  | 
| Remnant of mosaic, on the wall, thus probably very late Roman, Roman/Christian | 
|  | 
| Ample info on evolution of the Baptistry |

| The pediment again |

| Vaulting in Gothic aisle | 
|  | 
| Barrel vaulting in Romanesque nave | 
|  | 
| Note the non-Christian-looking little columns up high |

| Crossing...fascinating church! |
