There has been a church dedicated to St. Etienne (Saint Stephen) in Chinon since the 11th century but the current church was constructed between 1460 and 1490. It comprises a nave of five bays, two side chapels, a choir of two bays and a polygonal apse.
The flamboyant gothic influence is in evidence from the moment you step through the elaborate portal. The stained glass windows are by the master glass-maker Julien-Leopold Lobin who's workshops provided many of the windows for the 19th century church-building programme in the region.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
