The St Nicholas parish church was founded in the 1220s, with later additions including late 13th-century chancel and transepts and a 19th-century tower. The church is Grade I listed. Perhaps the most remarkable features of the church are the ornate rood screen, misericords and stalls which were transferred to the church from Chirbury Priory in Shropshire after the Dissolution of the Monasteries in the 16th century.
The south transept shows evidence of Montgomery's close association with the Herbert family. The centrepiece is the Elizabethan era tomb or church monument to Richard Herbert (died 1596) of Montgomery Castle, father of poet and Anglican divine George Herbert. This association is recalled in a memorial poem to a well-known local man J. D. K. Lloyd, who wrote this poem after the style of George Herbert.
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.
