Exploring the colorful streets of Lisbon

As I explored the vibrant streets of Lisbon, I couldn't help but notice the many colors that adorned the buildings. From the bright yellows of Praça do Comércio to the pastel pinks of the Ribeira das Naus, each street seemed to have its unique palette. But as I researched further, I realized that this was not just a matter of aesthetics. The tradition of painting buildings in different colors began in the aftermath of the 1755 earthquake that shook Lisbon to its core. The authorities decided to rebuild the city and introduced a law that required all buildings to be painted in different colors to prevent the spread of fire. This was a fascinating insight into how human design can be shaped by external factors beyond their control.
