Albenga Baptistery

Albenga is a small city on the Italian Riveria, dating back to pre-Roman times.

It most famous monument is this Baptistery, built around 400 CE. It survived largely intact until some nineteenth-century enthusiasts got hold of it and "restored" it.

But the mosaics, dating to the sixth century, survived the restoration.
