Here's a view of the collegiate church — l'église collégiale — in Saint-Aignan. It's a main feature of the town's "skyline." A collégiale is a church that, hierarchically, stands between a cathrédrale and an église paroissiale (a parish church). Both the cathédrale (presided over by a bishop) and the collégiale are home to a "college of canons" or religious community that holds daily worship services.
The Cadogan Loire guide says that the front tower was a 19th century addition to the much older Romanesque church at Saint-Aignan. It looks to me as if the top section — the belfry, I guess — is much newer than the old structure that it sits on. Just look at the difference in the stone.
Below is a close-in view of the church's old "porch" — the main entrance into the church — which is the street-level part of the tower in the photo above.
Above the front archway of the church tower are engraved the words RÉPUBLIQUE FRANÇAISE — LIBERTÉ ÉGALITÉ FRATERNITÉ, as you can see more clearly in the next image. That's the French revolutionary slogan. I've only seen it on one other church building, and that's over in the nearby town of Chémery. Unless memory fails...
The church's other tower, below, is different in style and architecture. It stands above the transept, which is the center of the cross-shaped building's floor plan.
Finally, I'll post this view of the church, taken, like the first photo in this post, from across the Cher River, but a little closer in.
Tomorrow I'll post some photos of less monumental subjects. Saint-Aignan street scenes...
