St. Jacob's church is easy to recognise from a distance as it has four spherical globes on the tower's helm edge. The three-naved Gothic brick hall church (built in 1334) has been the church of seafarers since the Middle Ages. It was consecrated together with St. Mary's and St. Peter's. Since the church did not suffer any damage during the 2nd World War, the boxed pew and historic organ are still intact. The small 'Stellwagen organ' is one of the best preserved examples of North German organs from the 16th century.
A lifeboat commemorates the sinking of the four-masted barque 'Pamir' in 1957. It is located in the north tower chapel and represents the 'National Memorial for Civilian Shipping' today.
St. Jacob's is a memorial site for international seafarers and placed in its vault beneath the Pamir chapel, which serves as a Columbarium (a place of memory), are the urns of those whose lives were intertwined with the sea. An ensemble of three-storey brick eaves houses built in 1601 stands in front of St. Jacob's. These served as residences for the pastors and preachers of St. Jacob's Church.
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.
