Step-by-step explanation:
The Piazza dei Miracoli, also known as the Square of Miracles, is located in Pisa, Italy. It is famous for its remarkable medieval art, particularly the buildings known as the Baptistery, the Cathedral of Pisa (begun in 1063), and the campanile, or Leaning Tower of Pisa (begun in 1173).
Visually, the Piazza dei Miracoli is an expansive open space, showcasing a blend of impressive architecture marked by geometric façades and distinctive striped patterns of grey and white stone. The three-dimensional façade of the cathedral is particularly striking with open arcades screening walls decorated in contrasting stripes. These elements contributed to a new complexity in architectural design during the medieval period, enhancing the location's grandeur and reverence as a centre of religious and cultural activity. The Leaning Tower of Pisa offers an iconic image known worldwide, tilting due to unstable foundation soil but still standing impressively as part of the complex.
