St Martin's Church (Sankt Mortens Kirke) is one of the city's medieval churches. Known from records since approximately 1280, it is believed to have been built and put into service around 1200. The building was constructed as the city's parish church. It is dedicated to St Martin of Tours considered its patron saint.
The church is a Gothic structure built with bricks. The oldest parts of the church are from the 1220s. The tower was added in the 15th century but the baptismal chapel and the porch were completed as late as the 1850s.
The arches bear a portrait of St Martin. There are many frescoes of the period; one depicts him as a soldier sitting on his horse, while he cuts a piece of his officer cap and gives it to a beggar. The church's first organ, installed in 1587, was made by Hans Brebus (d. 1603), a Flemish organ builder who practiced in Denmark and Sweden. The altarpiece (1667) of 6m height is decorated with figures wearing grotesque masks or with mustaches, some of whom are stooping low) and is attributed to thewoodcarver Abel Schrøder (1602-1676) who was also the church's organist for forty-two years. Today's Frobenius organ dates to 1975. The pulpit was built by Abel Schrøder's father.
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.
