Designed in 1871 and built five years later, the Historic Landmark Building at the Pennsylvania Academy of the Fine Arts is considered the first building that put Furness on the map, so to speak. Furness won the competition along with his partner George Hewitt to design the academy’s art museum and school building. Furness took a leaf from the industrial boom of Philadelphia at the time, taking groundbreaking measures to create a modern building with features like skylights, sandblasted ornamental designs inside and out, and steel and iron construction. The historic building continues to be used as a gallery and studios to this day and has undergone at least two major restorations.

The blocky building at 22 South 40th Street may not be the most historic, nor the most heralded building on this list, but in a time when so many of Furness’s works are getting—or already have been—torn down around the city, it’s important to note the ones that still have some life ahead. This place definitely falls into that category. Designed in 1874, this three-story building is the subject of an upcoming $2.5 million restoration by U3 Ventures, which bought the place last year. They plan to restore the building, which is currently covered in tin siding, to its early 20th century glory. When it’s finished, the interior should be something pretty spectacular—it already has columns and 17 foot high ceilings on the first floor.

Frank Furness designed a number of train stations throughout the Philadelphia region, some of which have been lost to the wrecking ball. But some of his smaller works continue to serve as stations along the SEPTA Regional Rail, including the Mt. Airy Train Station on the Chestnut Hill East Line. It dates back to 1875 and stands out for its gabled roof and Queen Anne Stick-style architecture. (One of Furness’ biggest train stations that’s still standing is the Wilmington Train Station in Delaware.)

One of the few-remaining banks in Philly by Furness is the Centennial National Bank in University City. The architect designed this hulking building in 1876, his first project after parting ways with partner George Hewitt. Today, it serves as an alumni center for Drexel University and it has a spot on the National Register of Historic Places. The nomination called it “one of the best pieces of architecture in West Philadelphia.”

Furness’s craftsmanship is on prominent display along the Schuylkill River along the historic Boathouse Row. The architect brought his style and flair to the Undine Barge Club in 1882, at a time when the boathouse was nothing more than a shack. He also designed the club’s Castle Ringstetten, a social gathering spot that’s about three miles upriver from the boathouse.

The Furness-designed church that currently stands at 21st and Chestnut streets is actually the congregation’s third edifice. Furness had especially strong ties to the church—his father Reverend Dr. William Henry Furness was a long-time minister of the First Unitarian Church. Furness designed the sacred space in 1883 at the bequest of his father’s good friend Ralph Waldo Emerson. The city’s first Tiffany glass window was installed here.

One of the most iconic buildings that graces the University of Pennsylvania’s campus is the Fisher Fine Arts Library, designed by Furness in the late 1800s. Its fiery red brick facade is just as ornate and eye-popping as the library’s stunning interiors. In fact, Louis Kahn preferred to teach his studios in the Furness building over the actual PennDesign School next door. After it opened in 1891, the library underwent a major restoration by Venturi, Rauch and Scott Brown and was renamed the Anne and Jerome Fisher Fine Arts Library. Today, it’s home to the university’s arts and architecture collection and a gallery.

Mt. Sinai Cemetery is one of the oldest and active Jewish cemeteries in Philly, dating back to 1854. Furness didn’t bring his touch to the cemetery until 1892, when he designed a chapel for the cemetery. It’s short and stout, but features the architect’s tell-tale details like Moorish windows.

Toward the later end of Furness’s career, Philly began to see a more reserved and conservative version of the architect’s work. Take the Girard Trust Bank building, for example, which Furness designed in 1905 as an ode to the Pantheon in Rome. Fun fact, though: Next door to the domed building used to be home to a 12-story Furness high-rise, the headquarters of West End Trust and Safe Deposit Company. You can see a portion of it in the photo below, before it was razed. Today, it’s home to the Girard Building, which is now the Ritz-Carlton Hotel.
