The Church of the Addolorata is a Romanesque-style basilica church in Acqui Terme. The church is dedicated to the Marian devotion of Our Lady of Sorrows, however, the church is also called San Pietro, since it was once attached to what was once the adjacent Benedictine monastery of San Pietro.
The layout we see today was built in the 11th-century at the site of a late 6th-century paleochristian church located just outside the city walls. It had three naves with an octagonal bell-tower at the southern apse. The simple brick facade has protruding pilasters and shows a trend towards verticality. After 1720, with the closing of the monastery, part of the church was rededicated to the Addolorata. It underwent major restoration after the First World War, that stripped much of the decoration, giving the interior a white-washed simplicity. The apse and the base of the bell-tower retain medieval traces.
The interior conserves a 15th-century Deposition fresco and two 16th-century canvases depicting Christ Crowned with Spines and Christ before Pilate. The wooden statue of the Madonna Addolorata dates to 1720.
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.
