The Duomo (Cathedral) of Enna, a notable example of religious architecture in Sicily, was built in the 14th century by queen Eleonora, Frederick III's wife. It was renovated and remodeled after the fire of 1446. The great Baroque facade, in yellow tufa-stone, is surmounted by a massive campanile with finely shaped decorative elements. The portal on the right side is from the 16th century, while the other is from the original 14th-century edifice. The interior has a nave with two aisles, separated by massive Corinthian columns, and three apses. The stucco decoration is from the 16th and 17th centuries. Art works include a 15th-century crucifix panel painting, a canvas by Guglielmo Borremans, the presbytery paintings by Filippo Paladini (1613), and a Baroque side portal. The cathedral's treasure is housed in the Alessi Museum, and includes precious ornaments, the gold crown with diamonds known as the 'Crown of the Virgin,' Byzantine icons, thousands of ancient coins, and other collections.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
