1. Graeme Park – Horsham
One of Montgomery County’s most historically significant sites, Graeme Park is home to the Keith House, the only surviving residence of a colonial Pennsylvania governor. Built in 1722, this Georgian-style mansion offers a rare glimpse into early 18th-century architecture.
The house’s symmetrical façade, classic brickwork, and steep-pitched roof reflect the era’s refined yet restrained design. Now a National Historic Landmark, Graeme Park invites visitors to step back in time and appreciate both its historic and architectural value.
2. Bryn Athyn Historic District – Bryn Athyn
The Bryn Athyn Historic District is a treasure trove of craftsmanship and design, consisting of three magnificent structures: Cairnwood Estate, Glencairn Museum, and Bryn Athyn Cathedral.
- Bryn Athyn Cathedral, completed in 1919, blends Gothic Revival architecture with the spiritual vision of the New Church. It features hand-cut stone, detailed stained glass, and intricate wood carvings—many of which were created by local artisans.
- Glencairn Museum, once a private residence, is a stunning Romanesque-style castle with sweeping staircases, vaulted ceilings, and over 90 rooms. It now houses religious art from around the world.
- Cairnwood Estate, designed by Carrère and Hastings (of New York Public Library fame), is a Beaux-Arts mansion that once served as the home of industrialist John Pitcairn. It exemplifies the opulence of the Gilded Age.
This district is a must-see for lovers of architecture, art, and history.
3. Pottsgrove Manor – Pottstown
Built in 1752 for ironmaster John Potts, Pottsgrove Manor is a standout example of colonial Georgian architecture. With its bold stone exterior, formal symmetry, and refined interior detailing, the manor showcases the affluence and craftsmanship of early Pennsylvania elites.
Located near the Schuylkill River, the property has been restored and preserved to reflect life in the mid-1700s. It’s an educational and aesthetic gem in the western part of the county.

4. The Stoogeum – Ambler
While it may not have the same historic credentials as others on this list, The Stoogeum is a quirky architectural curiosity that celebrates a different kind of legacy—that of The Three Stooges.
This three-story building combines traditional elements with a modern twist to create an engaging and highly personalized museum experience. The layout and design cleverly blend memorabilia with multimedia exhibits, making it a one-of-a-kind space that’s full of character.
5. The Highlands Mansion and Gardens – Fort Washington
Tucked into 44 acres of preserved land, The Highlands is a gorgeous example of late Federal-style architecture. Built in 1796, the stone mansion features refined details like Palladian windows, an oval drawing room, and a grand staircase.
The surrounding formal gardens and woodlands enhance the architectural splendor, creating a picturesque setting that hosts events, weddings, and public tours. It’s one of Montgomery County’s most beautiful estates, both inside and out.
6. Abington Art Center and Alverthorpe Manor – Jenkintown
Alverthorpe Manor, now home to the Abington Art Center, is a striking example of early 20th-century modernism. The manor’s Art Deco elements, clean lines, and integration with nature reflect a progressive architectural philosophy that stands in contrast to the county’s more traditional styles.
Originally the home of philanthropist Lessing J. Rosenwald, this 27-acre estate continues to inspire creativity through contemporary art exhibitions and public programs—all within an architecturally significant setting.
7. Peter Wentz Farmstead – Worcester Township
This well-preserved historic site transports visitors to 18th-century Pennsylvania German life. Built in 1758, the Peter Wentz Farmstead is a wonderful example of German Colonial architecture with its steeply pitched roof, central chimney, and exposed beams.
George Washington even used the farmhouse as his headquarters during the Revolutionary War. Its enduring design and historic importance make it a cornerstone of Montgomery County’s architectural heritage.
8. Ursinus College Campus – Collegeville
If you love collegiate architecture, you’ll appreciate the diverse styles found across the Ursinus College campus. From the Gothic Revival beauty of Bomberger Hall to the contemporary lines of the Berman Museum of Art, the campus blends tradition and modernity with architectural finesse.
Walking through the campus offers a mini architectural tour, where ivy-covered buildings coexist with glass-and-steel additions—a reflection of the county’s evolving design sensibilities.
9. Green Lane Park’s Stone Arch Bridge
Tucked away in the scenic northern part of the county, the Stone Arch Bridge at Green Lane Park is a small but charming example of early infrastructure design. Built in the 19th century, the bridge’s strong stone masonry and classic arch design offer a nod to Pennsylvania’s history of engineering excellence.
It’s a quiet reminder that architectural beauty can often be found in the most unexpected places.
10. County Courthouse – Norristown
No list of architectural landmarks in Montgomery County would be complete without mentioning the Montgomery County Courthouse in Norristown. The original courthouse, built in 1854, features Greek Revival architecture with imposing columns and a classic dome.
Subsequent expansions have added modern structures, but the historic core remains a symbol of the county’s governance, resilience, and architectural legacy.
