Step into a rare piece of Philadelphia history at 523 Fairmount Avenue, an exceptional 19th‑century residence built as part of the estate of Stephen Girard—one of the city’s most influential figures and the wealthiest man in America at that time. Set in the heart of Northern Liberties, this home offers a scale, level of renovation, and historic pedigree that are nearly impossible to find at this price point in such a premier location. The original brick façade exudes timeless curb appeal, while inside, the home seamlessly blends preserved architectural character with modern comfort. Five spacious bedrooms, three full baths (including a serene primary suite with soaking tub), and two half baths are spread across four grand floors. High ceilings, rich wood floors, custom millwork, and thoughtfully restored details create an atmosphere that is both warm and sophisticated. A true standout is the expansive rear yard—a lush, private urban retreat rarely found in this neighborhood. Multiple outdoor spaces invite relaxation, gardening, and entertaining. The full finished basement adds even more versatility, perfect for a home gym, media room, office, or playroom. Just steps from acclaimed dining, boutiques, and cultural destinations, this home sits in a neighborhood shaped by William Penn’s original vision and celebrated today for its vibrant energy and architectural charm. 523 Fairmount Avenue is a unique opportunity to own a beautifully restored piece of Philadelphia’s past while enjoying the best of modern city living.
