Church of the Poor Clares is a red brick Gothic church with a few Renaissance touches built between 1582 and 1602 on the site of a previous wooden church and hospital. Officially named the Church of the Ascension of the Virgin Mary, it is known locally as the Church of the Poor Clares as it was the home of the Order of the Poor Clares from 1619 until 1835.
The building was turned into a warehouse and later a fire station during the Prussian occupation of the city. Renovated at the end of WWI and reconsecrated in 1923, the church now functions as the city's main garrison church, serving the 10,000 or so military personnel stationed in Bydgoszcz. Of the church's many wonders, of particular interest is the early 17th-century distemper ceiling inside the nave, featuring 112 polychrome panels of beautifully executed flower designs.
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.
