I have a Full Degree in Italian History of Art, so besides Vatican and Colosseum tours I lead my groups (foreigners and Italians) in specialized thematics tours, as examples:
Augustus “Pater Patriae” in the Ara Pacis
Roman Paleo Christians Mosaics Tour
Trastevere Treasures (in Trastevere started the Christian Religion into the Roman Empire)
A Renaissance jewel – Villa Farnesina
Caravaggio: his life in Rome
Bernini and Borromini rivals
If you want cover to further the subject please don’t hesitate to contact me, I would gladly consider all proposals.
