The Da Ponte Fountain dates from 1666, replacing an older one on the same site. Its superstructure is in the shape of a bridge, surmounting an octagonal water basin surrounded by fifteen pilasters, each bearing the arms of local noble families who had contributed funds toward the fountain.
A subaquatic aqueduct connected the island of Koper to the mainland as early as the end of the 14th century. By the 16th century, the 10,000 inhabitants of the city were facing a water shortage, rainwater cisterns having become inadequate. In the 17th century, Niccolò Manzuoli recorded the city water supply, noting that a 2-mile distant spring at Colonna was piped to the island via wooden underwater tubes, some of which have been unearthed during excavations by modern archeologists.
The water spurts from four mascarons at the base of the arch. The fountain was used as a source of potable water until 1898.
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.
