The Apollon Theatre, whose origins date back to the late 18^th century when it was converted from the pre-existing old church dedicated to San Filippo Neri and then entirely renovated in 1887, is an authentic treasure of its kind the recent restoration works returned the original splendour to. Especially, it was in operation in the 19^th century and in the first half of the 20^th century when it was initially run by the Accademia del Teatro (The Academy of the Theatre). The interior of the theatre remarkably creates suggestions for the harmony of its spaces and the elegance of its floral decorations with festoons, racemes of acanthus and grotesques, enhanced by the gorgeous velarium ceiling with dancing cupids in a circle around Apollon. Today the theatre has reacquired its fundamental cultural and social role not only across the community of Mondavio.
