Docomomo US invites participants to an extraordinary weekend exploring the architecture, planning, and design legacy of Philadelphia and its surrounding region through the work of Louis Kahn, Frank Lloyd Wright, Robert Venturi, I.M. Pei, Oskar Stonorov, and Wharton Esherick. Guided by Dan Macey, President of the Docomomo US/Philadelphia chapter, and William Whitaker of the University of Pennsylvania, the program combines landmark buildings, private residential tours, archival access, and intimate social gatherings. The tours will leave from the iconic Loews Philadelphia Hotel in the PSFS Building, one of the country’s defining early skyscrapers of the International Style and completed in 1930 by the prominent architectural partnership of George Howe and William Lescaze.
