The imposing Church of the Holy Trinity was built by Franciscan monks in 1420-1514. In 1480, the Chapel of St Anne was constructed alongside the church. This towering Gothic building, adjoining a former Franciscan monastery (now the National Museum), is among the best preserved buildings in the city.
The altar is offset by a lofty whitewashed interior and the wide expanse of floor is cobbled with tombstones, including an epitaph of the Marquis of Oria who died in Gdansk. The marquis donated over 1,000 valuable books to the city library. The church contains the oldest surviving pulpit in Gdansk – it dates from 1541 and is another remarkable example of local wood carving. Beside the church is a half-timbered galleried house dating from the 17th century.
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.
