Topped by a pair of mismatched towers, Ascoli's duomo was built in the 16th century over a medieval building and dedicated to St Emidio, patron saint of the city. In the Cappella del Sacramento is the Polittico, a polyptych executed in 1473 by Carlo Crivelli. The crypt of Sant Emidio has a set of mosaics any ceramicist will appreciate.
Next to the cathedral and something of a traffic barrier today, the battistero (baptistry) has remained unchanged since it was constructed in the 11th century.
