Église Notre-Dame ('The Church of Our Lady') dates from the 12th century, and chiefly from the 14th century. It is a sample of Tudor architecture due Calais was part of England for centuries. The church was damaged during the early wars between France and England, especially in 1346-47, after the Battle of Crécy. Many of the kings and queens of France and England prayed here; and John Bourchier, 2nd Baron Berners is buried in the church choir.
The church is large and has a fortress-like appearance. Its layout is in the shape of a Latin cross. There is a large nave with aisles, north and south transepts, a choir with choir-aisles, and a side chapel. A notable feature is the high altar, mostly completed by 1626, which has carvings and bas-relief. A pedestal and a statue are dated 1628, while two other statues were added in 1629, and the balustrades finished in 1648. Among the works of art is a painting by Peter Paul Rubens of the Descent from the Cross.
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.
