Farrell Pennsylvania USA Sculpture Dial 519
"Rising Rings" is a cast iron band 11 feet high by 17 feet in diameter with a hole that casts a beam of light onto a central ring monument on the equinoxes. The dial was commissioned by Dr. Swraj Paul, a steel mill owner, to honor his daughter Ambika who died of leukemia. This monument honors the inspiration her joy of life instilled in her father. At the central of the dial is a cast iron ring that holds a bronze image of her that is illuminated for several days twice a year. On two dates, Ambika's birthday and the anniversary of the mill's re-opening the noon sunlight passes through the circular opening in the larger ring and strikes markers on the inner ring. Miklos Simon created the portrait of Ambika mounted on the smaller ring.
 
Franklin Center Pennsylvania USA Equatorial Dial 139
A modernistic equatorial dial about 6 feet in diameter. The analemma shaped gnomon casts Eastern standard time onto a wide metal semicircle band. The hours with 10-minute marks are inscribed on the center of the equatorial band. This unique sundial tells the time, indicates the approximate day of the month and projects the zodiacal constellation signs as they are aligned with the sun and the earth in this era. It is accurate to within two minutes.

Kennett Square Pennsylvania USA Horizontal Dial 329
Dating from 1976, this "secret" garden room (once a sundial garden with boxwood parterre) was designed by Thomas Church and is on the western side of the 1908 Square Fountain pool. The ground level horizontal dial is limestone with an iron gnomon. Hour lines identified by Roman numerals; hours divided into minutes. Hour line distribution adjusted for style width. EoT engraved on PM side of dial face. Dial sits atop a large mortared stone base.
 
Kennett Square Pennsylvania USA Analemmatic Dial 328
37.2 ft x 23.8 ft. This is probably the world's largest analemmatic, unusually designed to show standard time directly. It took 8 years of daily readings to perfect the sundial, which is accurate to within 2 minutes. Hour markers are bronze Roman numerals. Minute lines inscribed in limestone curbing. The gnomon itself is a moveable pole that is set on an AM or PM daily curve. NASS member P. Kenneth Seidelman was instrumental in correcting this design in 1978.
 
Lampeter Pennsylvania USA Vertical Dial 545
A 32x64-inch cast stone vertical declining dial located 25 feet up a vertical column at the school's entrance. An EOT plaque is located below the dial.
 
Lewisburg Pennsylvania USA Equatorial Dial 445
A large, ornate equatorial dial of brass sits outside the physics department building. The dial is approximately 8 feet across. Two pillars with brass balls support the dial plate. Two more pillars with ball support the gnomon wire. To add a flourish, the north most pillar and ball have a spread eagle holding the gnomon wire in its mouth. Unfortunately this beautiful dial is tarnished by age, with the analemmas for each hour barely visible on the dial plate. The gnomon wire, broken sometime in the past, is jury-rigged and tied together in the middle, resulting in a unkempt look to such a fine dial. A dark, round stone base, perhaps made of slate, approximately 8 foot in diameter supports the dial and pillars. The stone sits upon a 10 x 10 foot concrete pad.
 
Philadelphia Pennsylvania USA Equatorial Dial 741
An equatorial projection dial with a 12 inch diameter stainless steel equatorial ring incised with Arabic hour numerals that project onto a grooved central support shaft of Cipollino and Carrara marble set on a bluestone foundation.

Philadelphia Pennsylvania USA Vertical Dial 149
On wall of the passage from hallway to kitchen inside the house, just for exhibition. 9.5 × 19 inches, rough wood painted in black, roman numerals from 8 am to 5 pm on 1.5 inches wide frame, it was for hanging on a declining wall. Black iron gnomon rod, 1 foot in length, is supported with iron vine which is fixed to a point on the dial plate about 1.5 inches from the noon line. Unfortunately, the gnomon seems twisted, so that it points down over the noon line, like those for dials facing true south. Admission fee: $5.00 for guided tour. No photo allowed inside.
 
Philadelphia Pennsylvania USA Horizontal Dial 148
Horizontal dial approximately one foot diameter mounted on old stone atop a 3 foot stone pedestal. It is sitting against north wall of the garden and not aligned in proper direction. Plaque at the base states "This sundial stood for over a century in the gardens of Dorchester House, Park Lane, London, England. Presented by The Soroptomist Club of Philadelphia, December 23, 1935". This may be true for the dial plate because the hour angles indicate a latitude of 51°, the London latitude. It may not be true for the gnomon, whose style angle is 40°, the Philadelphia latitude. Access by taking guided tour, $5; then ask for garden.

Swarthmore Pennsylvania USA Vertical Decliner Dial 35
Modern design for a vertical dial declining 20.5° east on a brick wall. The gnomon is a twisted sheet of bronze, casting shadows onto granite hour marks. The dial was designed by Marti Cowan using Waugh's formulae for vertical dials. Frederick Orthlieb, professor and chair of the Dept of Engineering at Swarthmore "had a part in locating the bent-plate gnomon so as to give correct indications on the vertical wall… As installed, the gnomon's indicating edge (which lies on a Polar Axis) casts a quite short shadow in Autumn and Winter and requires some observing skill to make a close estimate of indicated time, but in Spring and Summer the longer shadow moves over the granite hour marks very plainly."
 
University Park Pennsylvania USA Armillary Dial 64
A bronze armillary dial with meridian and equatorial rings and Arctic and Antarctic circles on a stone pedestal.
