Lock Ridge Park:
Alburtis, Pennsylvania
The History of Lock Ridge Furnace
Lock Ridge Furnace began its life in 1868, built by the Lock Ridge Iron Company along the Catasauqua and Fogelsville Railroad during a period when the Lehigh Valley was a booming center of anthracite‑fueled iron production. The Thomas Iron Company acquired the site shortly afterward and operated two furnaces—designated No. 7 and No. 8—that used a hot‑blast process to burn anthracite, a technology introduced to the region by industrial pioneer David Thomas. Despite periodic upgrades, the furnaces gradually fell behind modern steelmaking methods. They ultimately ceased production in 1921 and were later dismantled for scrap, leaving behind the massive stone structures that still stand today.
With the industrial era fading, the Butz family donated the remaining furnace grounds to Lehigh County, which transformed the property into Lock Ridge Park in 1976. Today the 59‑acre park preserves the atmospheric ruins as the Lock Ridge Furnace Museum, offering tours, walking paths, and access to Swabia Creek. The site is listed on the National Register of Historic Places and remains a striking monument to the region’s iron‑making heritage—its arches, stone walls, and open greenspace blending industrial history with a serene public landscape.
A Trip Back In Time to Lock Ridge Park
Lock Ridge Park has been on my radar for quite a while. Why I haven’t made it to this historic site until 2026 is a mystery to me. Sometimes I get a little too comfortable in my usual photography haunts or maybe I’m intimidated by the prospect of photographing a historic site, wondering if I’ll do it any justice. Imposter syndrome is a real thing with photographers. Whatever the reason was, I finally made the trip this June.
With one vacation day burned and the entire morning to enjoy the park in relative peace, I only needed the weather to cooperate. It turned out to be a slightly overcast morning for the most part, providing soft diffused light to capture the park’s old stonework and 19th century craftmanship. I knew I’d be up against the clock before the sun beat away the clouds, so I tried to work quickly, but also thoughtfully.
The images and videos that follow will be in the order that I approached the entire shoot, starting with the carpenter’s house and ending with the stone bridge that crosses the nearby Swabia Creek. I hope you enjoy this little journey of mine. If you absolutely love any of the images, they can be purchased on my storefront at LehighValleyLandscapes.com along with hundreds of other photographs I’ve captured around the Lehigh Valley.
Upon entering the park and before my camera was even out of the bag, I was welcomed by several deer, a woodpecker and a black bird. Seemed like a very good start to the morning!
The Carpenter’s Shop
Upon entering the site, the very first structure you’ll likely encounter is the carpenter’s shop. It has two expertly crafted archways on either end of the building. The care that went into building these arches still shines through 160 years after it was first constructed. The ceiling of the structure has been lost to time, but the ruined walls are still present. I’ve been through the park on the weekends, and this seems to be a very popular spot for portrait photographers and their clients.
The archways are the clear points of interest on the carpenter’s shop, so I captured a single portrait shot of the archways embedded in one another. I then moved to the opposite end of the building to grab a wider landscape photograph to show off the length of the structure, the ruined walls and the arches as well. Finally I moved a bit further out to capture a more contextual shot that included more of the landscape.
Most of the structure photographs were captured from a low angle to make them feel a bit larger than life, but also to capture the blue skies and towering trees that fill out the park.
Once my photography of the carpenter’s shop was complete, I walked a short distance over to the trestles. I really should have paid more attention to the information boards around the park, but I will have to assume these were used to cart in raw materials to the furnace. Next time I visit the park, I’ll have to read up more! I grabbed a similar embedded archway shot of the trestles as well as a wider view for additional context.
The Trestles
The Arched Windows
Walking to the west side of the main furnace complex, I encountered some of the more precarious parts of the ruins. Some of the area is fenced off for visitor’s protection, however there are two beautifully aged arched windows embedded into the west wall that could not be ignored. I captured these from two angle. The first capture was from straight on after short walk uphill. The second capture was closer up and from below. I chose to process the 2nd shot as a dramatic black and white photograph. I just felt better that way.
The Primary Structure
The primary structure of the complex is evident as soon as you enter the museum. Much taller and consisting of several buildings, it demands your attention. The west side of the structure housed two furnace rooms as well as the engine room. The east side of the structure consisted of the cast house and the molding shops. I spent a good bit of time walking around this large area attempting to find the best angles that would capture these historic areas. Hopefully I did them some justice. The light was still cooperating at this time, which direct sunlight beginning to break through the clouds and cause some challenges with shadows. I tried to use the shadows in my favor where possible.
The Wooden Footbridge
To the west of the main building, a wooden footbridge rests on historic stone walls. It links the weighmaster’s house to the rest of the complex and crosses over a peaceful walking path that guides visitors into the calm of the park’s forested areas.
Stone Bridge Over Swabia Creek
Swabia Creek runs along the east side of the complex. For those feeling adventurous, a narrow path leads down to the water, winding through brush to a stunning spot where the creek passes under a double-arched stone bridge and cascades over a small waterfall. I captured shots from both sides of the bridge, and they ended up being some of my favorite photos from the trip—and also the last ones I took at Lock Ridge Park. I hope to return in the fall to see the scenery awash in colorful foliage. This collection of images captures my journey around the park.
