The Dale Furnace and Forge Historic District was listed on the National Register of Historic Places in 1991. Portions of the content on this web page were adapted from a copy of the original nomination document. 
Dale Furnace and Forge Historic District is located north of the village of Dale along the West Branch of the Perkiomen Creek. It lies in a valley, with a steep hill to its west, and land gradually sloping off to its east. The district consists of both architectural and archaeological resources. These include the furnace mansion, barn, horse barn, office, a worker's house, and the archaeological remains of an additional worker's house. There are also the remains of two iron furnaces, a forge, and the dam breast. The resources in this district are primarily constructed of stone.
We are fortunate that there is an excellent map of Dale Furnace and Forge available that dates back to 1835, showing the location of the principal structures of the iron plantation. Shown on the map, flanking the creek are the ironmaster's house, the barn, horse barn, bake oven, wash house and smoke house, worker's housing, furnace, forge, charcoal house, counting house, and the dam. A number of additional dwellings and attendant structures were located north of the furnace but are no longer standing.
With the number of resources in the district which are still extant, or whose location is still readily apparent, Dale has excellent integrity.
The complex includes the following resources:
1. horse barn, c. 1850
The horse barn measures 36' by 20'. It is constructed of stone. At this time the building is roofless.
2. bank barn, c. 1850
The barn measures 65' by 35 1/2'. This is a rather typical bank barn, with stone ends and vertical plank siding.
3. shed, 20th century - noncontributing
This is a frame shed with batten siding.
4. ironmaster's mansion, 1791, 1827.
The north end of the mansion, which is three bays wide, was built in 1791, in the Federal style. This is also reflected in the interior detailing and mantels. The south end of the mansion, which is two bays wide, and its attendant porches and ell were added in 1827. The interior detailing reflects that period. Overall, the house is five bays wide and four bays deep, the fourth bay in the ell. The main house has a chimney in each end wall, while the ell has one in the rear. The stone on the south end of the house has been stuccoed. The building retains many of its original details, including the arched front doorway with keystone, which dates from the 1791 mansion. On the south end the basement wall is exposed, and there is a two story gallery.
5. smoke house and wash house, c. 1827
The wash house is constructed of stone which has been stuccoed, and has a slate roof. The building is banked, two stories high on the west side, one story on the east. The building is three bays wide and one bay deep, and is located at the southeast corner of the furnace mansion. There are doors on both levels. The stone smoke house is attached to the south side of the wash house. It is approximately 8' square, with a gable roof. Only the east side of what appears to be the original tile roof is still extant.
6. archaeological sites
6A. worker's house ruin
This stone house appears to have been of similar construction to the extant worker's house directly to its west. The walls are still standing to what appears to have been a two story stone house with gable, measuring 27' 3" by 16' 10".
6B. stone furnace stack, c. 1791
Substantial remains of the furnace stack are located a short distance downstream from the forge foundations.
6C. bank iron furnace, 18th century
A short distance from the ruins of the forge, built into the bank, are the remains of an early furnace, lined with stone. The bosh of the furnace, which is clearly visible on top of the bank, measures nine feet in diameter. This may be the remains of Mt. Chalfont Furnace, which predated Dale.
6D. forge foundations and race, c. 1804-1811
Only remnants of the forge building remain, principally one corner of the foundation and scattered traces of the rest of the foundation. The original building was 44' 9" by 41' 6" with 12' high walls. The races that served the two undershot water wheels are still largely intact, as are some of the masonry arches bridging the race.
6E. remnants of dam breast
There are substantial remains of the stone dam which originally contained a pond which served the furnace and forge. The footprint of the pond is visible, but is not within the district.
7. worker's house, c. 1830
Constructed of stone, this is the only extant worker's house in the furnace complex. It is two and a half stories, and measures 22' 10" by 17' 10". It has six over six windows. A porch, a clapboard ell, and dormers are all of more recent vintage.
8. counting house (furnace office and post office), 1827, 1854
The Carpenter Gothic furnace office building is stone covered with stucco. The office was built in 1827, and substantially rebuilt in 1854. The one and a half story building is approximately 15' by 20', with gable ends. An eclectic decorative cornice was apparently added at that time. There is a frame shed addition on the west side of the building which has batten siding, and appears to be 19th century.
Dale Furnace, an iron plantation, represents an important and relatively well-preserved iron plantation of the late eighteenth and early nineteenth centuries. The complex retains its general layout and scale, although the industrial component is primarily archaeological. Those remains, which are significant under Criterion D, are distinct and well documented (particularly with the aid of the extant 1835 map of the complex), and have the potential to yield important information about the furnace layout, the products manufactured there, and the lifestyles of the workers and ironmaster. Dale Furnace is notable for its architectural significance. Its mansion is representative in quality of ironmaster's mansions. It is also one of the most sophisticated examples of Federal style residences in the local area. The building has excellent integrity both on the exterior and interior. Also notable is the Carpenter Gothic office building (1827/1854), with its unusual bargeboards, a delightful example of vernacular architecture.
The Dale Furnace was built by Joseph and Thomas Potts in 1791 on the West Branch of the Perkiomen Creek. In 1792 the assessment records indicate that the property consisted of 250 acres, 17 horses, 3 cows, a saw mill, and a furnace. By 1799, Dale Furnace was listed as the property of Miles and Hobart. Much of the ore for the furnace was brought from the mines near present-day Boyertown. The furnace produced stoves, skillets, kettles, anvils, and other household items. By 1805, the property had increased to 318 acres.
A forge was constructed sometime between 1804-1811 and the works became known as the Dale Iron Works. There are accounts of ordnance being dug at the site, possibly supporting the claim that the furnace produced small cannon balls and canister shells during the War of 1812. By 1820, the furnace was owned by Dr. Jacob Loeser. Under his management, the furnace was "blown out" c. 1821-1822. Loeser died in 1823, but the property remained in his name until 1826, when it was sold to George Schall and his son David, who purchased the property for $11,900. For almost forty-five years, David Schall ran Dale Forge.
There is no evidence that the furnace was ever in blast after 1822. Instead, the center of activity became the forge. The forge was described as having two hearths, and two hammers -- one of 500 pounds, and the other 600 pounds. They were each operated by undershot water wheels at the gable ends of the building. Blast for the hearths was supplied by two large bellows operated by an overshot wheel. Most of the pig iron used in the forge after the closing of the furnace came from Mary Ann, with some from Joanna and Hopewell Furnaces, all located in Berks County, and Hampton Furnace, just across the Lehigh County line. The forge produced both bloom and bar iron. In addition, it produced finished products including chisels, hinges, sledges, hammers, axles, railroad car axle trees, plows, etc. Based on the account books, business at the forge appears to have slackened after 1853. When Hampton Furnace, the last of their suppliers went out of blast in 1868, Dale Forge closed as well. The completion of the Colebrookdale spur of the Reading Railroad in 1869 to nearby Barto came too late to revive the forge.
David Schall died at Dale Farm on January 26, 1877 at the age of seventy six. The Dale Furnace mansion has remained in the Schall family until the present day.
