Santissima Trinità is a Romanesque-revival church in the city of Potenza. The church is now infamous as hiding for 17 years, the body of Elisa Claps, a young woman murdered by Danilo Restivo in 1993. The parish priest at the time had denied permission for the police to search the church despite it having been the last place the young woman was seen alive. The church was only searched after Restivo was arrested in England for the murder of Heather Barnett.
Documents point to a church at the site since the 1178. Further refurbishments followed over the centuries; however this romanesque-style church was razed by an earthquake in 1857. Few traces of the previous church remain; it appears the reconstruction, begun in 1872 diverged in layout and structure, changing the church from a structure with three naves to a single nave church. The interior decoration of the church was done mainly in the 1930s, with frescoes by Mario Prayer.
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.
