Masonic Temple Philadelphia

Philadelphia, PA · est. 2007

Completed in 1873, Philadelphia's Masonic Temple rises near City Hall as one of the great monuments to American Freemasonry. Home to the Grand Lodge of Pennsylvania, its interior unfolds as a tour of architectural styles, with lodge rooms evoking Egyptian, Gothic, Renaissance, and other themes, all wrapped in acclaimed stonework. Its scale and prominent setting reflect the fraternity's deep influence in the civic and social life of nineteenth-century America.

Reading Terminal & Market

Philadelphia, PA · est. 2003

Opened in 1893, the Philadelphia and Reading Railroad's Terminal Station carried passengers into the heart of the city until 1984. Its vast train shed, designed by engineer Joseph H. Wilson, was a marvel of its age, built when competing railroads raced to erect terminals that were as beautiful as they were useful. Beneath the shed, the Reading Terminal Market — descended from Philadelphia's colonial-era outdoor markets — opened in 1892 and still bustles today.

PSFS Building

Philadelphia, PA · est. 2005

Completed in 1932 at the depths of the Great Depression, the Philadelphia Saving Fund Society Building rose as America's first International Style skyscraper—a sleek tower of glass, steel, and stone that rejected the ornate columns and cornices then expected of a bank. Designed to broadcast modernity and stability, it embraced cutting-edge structural engineering, high-speed elevators, and air conditioning, announcing that the future of American architecture had arrived on Market Street.

Sigma Sound Studios

Philadelphia, PA · est. 2015

When engineer Joseph Tarsia opened Sigma Sound Studios in 1968, he gave a home to what became known worldwide as "The Sound of Philadelphia." Working with producers Kenny Gamble, Leon Huff, and Thom Bell, the studio's lush, string-swept records by The O'Jays, the Stylistics, and others helped define soul music in the 1970s. Its reputation for sonic craft grew so large that artists like David Bowie and Stevie Wonder made pilgrimages to record within its walls.
