Quattro Canti was laid out on the orders of the Viceroys between 1608-1620 by Giulio Lasso and Mariano Smiriglio at the crossing of the two principal streets in Palermo, the Via Maqueda and the Corso Vittorio Emanuele.
The piazza is octagonal, four sides being the streets; the remaining four sides are Baroque buildings, the near-identical facades of which contain fountains with statues of the four seasons, the four Spanish kings of Sicily, and of the patronesses of Palermo, (Christina, Ninfa, Olivia and Agata). The facades onto the interchange are curved, and rise to four floors; the fountains rise to the height of the second floor, the third and fourth floors contain the statues in niches. At the time the piazza was built, it was one of the first major examples of town planning in Europe.
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.
