St. Peter's Square (Piazza San Pietro) is a large plaza located directly in front of St. Peter's Basilica in the Vatican City, the papal enclave inside Rome, directly west of the neighbourhood or rione of Borgo.
At the centre of the square is an ancient Egyptian obelisk, erected at the current site in 1586. It was made of red granite and is 25.5 metres tall. The obelisk was originally erected at Heliopolis, Egypt, by an unknown pharaoh.
Gian Lorenzo Bernini designed the square almost 100 years later, including the massive Tuscan colonnades, four columns deep. A granite fountain constructed by Bernini in 1675 matches another fountain designed by Carlo Maderno in 1613.References:
The eight towns in south-eastern Sicily, including Ragusa, were all rebuilt after 1693 on or beside towns existing at the time of the earthquake which took place in that year. They represent a considerable collective undertaking, successfully carried out at a high level of architectural and artistic achievement. Keeping within the late Baroque style of the day, they also depict distinctive innovations in town planning and urban building. Together with seven other cities in the Val di Noto, it is part of a UNESCO World Heritage Site.
In 1693 Ragusa was devastated by a huge earthquake, which killed some 5,000 inhabitants. Following this catastrophe the city was largely rebuilt, and many Baroque buildings from this time remain in the city. Most of the population moved to a new settlement in the former district of Patro, calling this new municipality 'Ragusa Superiore' (Upper Ragusa) and the ancient city 'Ragusa Inferiore' (Lower Ragusa). The two cities remained separated until 1926, when they were fused together to become a provincial capital in 1927.
