Who was the architect behind the design of Washington Arch?

The architect responsible for the design of Washington Arch is indeed Stanford White. This iconic structure, located in Washington Square Park in Manhattan, was completed in 1892 as a tribute to George Washington's centennial. Stanford White was a prominent architect of the Beaux-Arts style and played a significant role in the development of New York's architectural landscape during the late 19th and early 20th centuries.

White's design for Washington Arch features a grand and impressive monumental structure that draws inspiration from classical Roman arches. Its prominent position in the park and its artistic embellishments are reflective of White's mastery in blending functionality with aesthetic beauty.

The other options, though notable architects in their own right, are not connected to the Washington Arch. Richard Morris Hunt was associated with other significant buildings, such as the Metropolitan Museum of Art. Frank Lloyd Wright is known for his innovative designs, but not for this arch, and Louis Kahn's work emerged later and is characterized by a different architectural style. Thus, the connection between Stanford White and the Washington Arch reinforces the historical and cultural significance of the structure in New York City.
