The Milvian (or Mulvian) Bridge was an economically and strategically important bridge in the era of the Roman Empire and was the site of the famous Battle of the Milvian Bridge.
A bridge was built by consul Gaius Claudius Nero in 206 BC after he had defeated the Carthaginian army in the Battle of the Metaurus. In 115 BC, consul Marcus Aemilius Scaurus built a new bridge of stone in the same position, demolishing the old one. In 63 BC, letters from the conspirators of the Catiline conspiracy were intercepted here, allowing Cicero to read them to the Roman Senate the next day.
In AD 312, Constantine I defeated his stronger rival Maxentius between this bridge and Saxa Rubra, in the famous Battle of the Milvian Bridge.
During the Middle Ages, the bridge was renovated by a monk named Acuzio, and in 1429 Pope Martin V asked a famous architect, Francesco da Genazzano, to repair it because it was collapsing. During the 18th and 19th centuries, the bridge was modified by two architects, Giuseppe Valadier and Domenico Pigiani.
The bridge was badly damaged in 1849 by Garibaldi's troops, in an attempt to block a French invasion, and later repaired by Pope Pius IX in 1850.
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.
