The L'Enfant Plan is a design blueprint created by Pierre Charles L'Enfant in 1791 for the layout of Washington, D.C.. It aimed to establish a grand capital city with wide avenues, public squares, and green spaces, reflecting the ideals of democracy and order. The plan incorporated a grid system with diagonal avenues, connecting important landmarks. L'Enfant's vision included prominent sites such as the Capitol Building and the White House, emphasizing the importance of these structures in the nation's governance. Although L'Enfant faced challenges and was eventually dismissed, his foundational ideas significantly influenced the city's development and urban planning.
