At the end of the 17th century, the Dominican Order established a monastery in Aglona and built the first wooden church. After the church burnt down in 1699, a stone monastery building and the present church were built in its place in 1768-1780. The interior of the shrine was created in the 18th-19th century, but the pulpit, the organ, and the confessional were built at the end of the 18th century.
The church houses an extensive collection of paintings, sculptures, and artistic treasures, including the famous icon “Our Miraculous Lady of Aglona”, which is uncovered only during religious festivals. The painting is considered to have healing powers. In 1993, Pope John Paul II visited Aglona sanctuary. Extensive renovation works in the church and improvements of the surrounding amenities were carried out prior to this visit.
Every year on the 15th of August, pilgrims congregate in Aglona to mark the day of the Assumption of the Virgin Mary into Heaven.
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.
