The architecture of Philadelphia is a mix of historic and modern styles that reflect the city’s history. The first European settlements appeared within the present-day borders of Philadelphia, Pennsylvania in the 17th century with most structures being built from logs. By the 18th-century brick, structures had become common.
Georgian and later Federal-style buildings dominated much of the cityscape. In the first half of the 19th century, Greek revival appeared and flourished with architects such as William Strickland, John Haviland, and Thomas U. Walter. In the second half of the 19th century, Victorian architecture became popular with the city’s most notable Victorian architect being Frank Furness.
