Stora Mellösa Church was buit in the late 1100s. It was enlarged to the east in the 15th century and the porch and sacristy were added in the 16th century. The chapel of near Göksholm castle owners was built in the mid-1600s. The spire and some other parts were destroyed by fire in 1743. The restoration was made between 1830-1836.
The interior date mainly from the 1600-1800s. The font is original from the 12th century. There are two pre-Christian runestones in the churchyard.
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.
