The story of this building begins on August twenty-sixth, 1,107, when the first stone was laid. However, just 10 years into construction, a massive earthquake in 1117 nearly leveled the entire structure. The people of Cremona did not give up; they began an ambitious reconstruction in 1129, which is why you see such a fascinating mix of architectural styles today. Notice the grand rose window in the center, crafted by Giacomo Porrata in 1274. Below it, two heavy marble lions, sculpted in 1285, patiently guard the entrance. If you look higher, you will see a Renaissance-style upper section added much later, in 1491, proving that this cathedral is a living, evolving piece of history.
