The Temple of Valadier stands at the entrance of a high mountain cave near Genga and the Frasassi Caves. Built by Pope Leo XII, originally from Genga, in 1828 on the basis of a project by the architect Giuseppe Valadier, the temple has an octagonal-shaped plan and a domed roof covered with lead plates; inside there is a Madonna with a child, sculpted by Canova’s workshop, replaced by a copy, since the original is kept in the Genga Museum.
Originally the temple was designed as a refuge for Christians asking for forgiveness, thus making use of the nickname of “refuge of sinners”.
