See L'Enfant's original plan and vision for DC and the National Mall

In the 1790s, L'Enfant designed a capital defined by broad avenues, public squares, and long sight lines between major civic buildings. Much of his vision for the Mall was disrupted for decades and was finally realized through later 19th- and early-20th-century redesigns.

Paris and Boston were redesigned partly to combat cholera's spread

Georges-Eugène "Baron" Haussmann, who oversaw Paris's redesign in the 1800s, replaced many of the city's narrow streets with wide boulevards.

Americans touring the Louvre were inspired to create their own grand museums

The one-time royal residence was first transformed into a public museum in 1793 amid the French Revolution.

The Greek city of Alexandria in Egypt helped form the template for modern cities

It was designed by Dinocrates, who studied under Hippodamus, the father of urban planning. Hippodamus preached that urban planning should take into account function, culture, and politics. Dinocrates' design of Alexandria meant applying Hippodamus' teachings on a scale never before attempted.
