Cattedrale di Santa Croce

The convent of San Domenico dates back to the 13th century. The refectory of the Dominican convent has 16th-century frescoes attributed to Girolamo Ugolini. The convent now houses the museum of San Domenico as well as an auditorium.

The Abbey of San Mercuriale, also known as the Church of San Mercuriale, is an abbey completed around 1181 in Lombard Romanesque style after the previous structure burnt down in 1173. In the 14th century, the porch was replaced by the Gothic portal that still exists and the two side chapels on the façade were built as an extension of the structure and demolished in 1646. The apse was also rebuilt in 1585. In 1646, extensive reconstruction work was undertaken. The work concerned both the façade and the body of the church, with the aim of creating a well-lit interior environment. The 14th-century connecting portico was also demolished to make room for the two entrances to the side aisles. The tower of the Abbey of San Merculiare, at 75 metres long, is one of the highest in the country.

The co-cathedral of Bertinoro stands on the site of a small oratory, which was demolished at the end of the 16th century. It was built in the style of Bramante by order of Bishop Giovanni Andrea Caligari and was completed in the 17th century.
