Santissima Trinità is a Romanesque-revival church located on Via Pretoria 123 in the city of Potenza, Basilicata, Italy.
The church is now infamous as the seventeen year hiding place of the body of Elisa Claps, a young woman murdered by Danilo Restivo in 1993.
The parish priest at the time of Claps's disappearance had denied the police permission to search the church despite it having been the last place where the young woman had been seen alive.
The church was only searched after Restivo was arrested in England for the murder of Heather Barnett.
Few traces of the previous church remain; it appears that although the reconstructed building, begun in 1872, has just a single nave, the earlier structure had three.
