The Church of St. Mary and St. Radegund in Whitwell date back to different centuries. Various portions of the church were constructed in the 12th, 13th 15th and 16th centuries. However, the church has some more modern parts as well.
The church consists of a nave which has a south aisle of three bays, a chancel with south aisle in alignment with the east wall, a western tower and a south porch. Looking at the church, it is evident that the original church did not have aisles, and had a narrow chancel, divided by an arch. A narrow south aisle was added in the 13th century which was later widened in the 16th century. When the church was originally formed, it was of two separate manorial chapels. The bells and clock were installed after the death of William Spindler who passed them on to the church, and is now buried in its graveyard.
The churchyard also contains the Commonwealth war grave of a Hampshire Regiment soldier of World War I.
On Monday 16 April 2007 Whitwell's Post Office re-opened inside the church's bell tower. Although other post offices have been relocated to new locations on the grounds of local churches, it was the first of its kind in the country to be located inside the church. The idea to locate the new post office inside the church came from the church's vicar, after no other suitable location was found.
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.
