What impact did the Great Fire of London have on urban planning?

The Great Fire of London in 1666 had a profound impact on urban planning, leading to significant changes in how cities were designed and governed. Prior to the fire, London was characterized by narrow, winding streets and a lack of building regulations, which contributed to the rapid spread of the flames.

In the aftermath, city planners recognized the need for better urban design to prevent such disasters from occurring again. This resulted in the introduction of new building codes and regulations that mandated the use of fire-resistant materials and establishing wider streets to improve accessibility and allow for better fire-fighting efforts. The fire also initiated the development of a more organized layout for the city's infrastructure, which included improvements in sanitation and public health.

These changes set a precedent for urban planning across England and influenced the development of cities worldwide, showcasing the importance of safety regulations and structured urban design. The fire fundamentally shifted attitudes towards city layout and management, making the significance of B especially clear as it encapsulates the extensive reforms driven by the event.
