St. Lawrence's Church has a long and complicated history that goes back to sometime around the end of the 13th century. It is one of few medieval churches in Östergötland built entirely in brick, a circumstance which may be connected to there being a large number of German merchants active in Söderköping at the time, and it remains a fine Swedish example of Brick Gothic. The original church had the form of a basilica with a central nave and two aisles.
During a city fire in 1494 the church was damaged and subsequently rebuilt. An external belfry was erected in the 1580s. During its history, it has been reconstructed, renovated and altered on several occasions, but retains much of its medieval form and look. Externally, the church is dominated by its red brick façade, interspersed with blind arches and supported by brick buttresses. As it has no protruding apse, both the west and the east end of the church is marked by straight façades that end in crow-stepped gables. On the external wall of the vestry, St. Lawrence is depicted. During a renovation in 1965, an immured runestone was discovered and laid bare in one of the walls.
The interior today is a typical hall church, dominated by white-washed vaulting. Remains of medieval fresco painting has been laid bare during 20th-century restorations. The church also contains some noteworthy inventories, such as a late medieval altarpiece (possibly French), a triumphal crucifix (possibly made in Vadstena circa 1400), a processional crucifix from the 13th century and several medieval carved wooden statuettes of saints.
The church has been the venue for royal coronations in Sweden on two occasions. The first time was when Hedwig of Holstein, wife of Magnus III of Sweden, was crowned Queen of Sweden on 29 June 1281. The second was when Birger Magnusson and Martha of Denmark were crowned King and Queen of Sweden in the church in 1302.
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.
