Perched on a ridge between two river valleys, with views over the Sibillini Mountains, the ancient ducal city of Camerino is a small but impressive hill town on the border between the provinces of central Marche and Umbria. Its attractive old centre has seen very little change for centuries. The narrow main street takes you from the fortress of the Borgias (1507) to the principal square, with the Cathedral, the Archbishop’s Palace and the Ducal Palace. The porticoed courtyard of the Ducal Palace is partly attributed to the great 15th century architect Pontelli. The grand architectural complex of San Domenico, built between the 13th and 16th centuries, has been restored and now houses fine works from the Camerino School of painting. Another fine gem is the Teatro Marchetti built in 1856.
