The church of the suburb of Guibray, situated outside the walls of Falaise and to the south, occupies the primitive site of a pagan sanctuary, transformed into a chapel, in the Merovingian period, before 650.
In c. 1000, a new church was built, and re-worked between the end of the 11th century and the end of the 12th century, on a Romanesque plan with a central nave, two side aisles and a short transept, at the instigation of the abbey of the Trinité in Caen. The church is a dependency of the abbey of Caen like all the churches of Falaise through a donation in 1066 by the lord of Falaise, Mézidon and Ecajeul. The unity of the building was significantly disrupted by numerous re-workings, from the 13th century, but the façade from the 12th century has been preserved as well as the chevet from the end of the 11th century, with its three apses on several floors, very like those in Saint-Nicolas in Caen. The choir, stripped of its neo-classical decoration in 1986 has had its Romanesque arcatures restored to it. Some interesting Romanesque capitals top the pillars of the transept, choir and its side aisles.
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.
