Chattanooga Tennessee USA Horizontal Dial 670
An 18 foot diameter horizontal dial of concrete and pebble with a cast bronze figure of a boy with outstretched arm, the 8 foot high finger tip of which serves as a point-in-space gnomon. The dial face includes hour marks and declination lines. An open book plaque on the bronze statue base gives instructions. Substantial surrounding building clutter blocks the sun for much of the day, rendering the dial without shadow.

ca 6'cylindrical segment, about 3' high Stainless steel Large equatorial, corrected for longitude. Nodus is a hole on a horizontal gnomon rod running E/W across face. Can compensate for DST by shifting dial via bolts/slots in base. Solstice lines run along top/bottom edge of cylinder. Built by Fabricators Inc., Chattanooga TN
Knoxville Tennessee USA Horizontal Dial 166
78" w x 168" h x 78" d Steel, brass & etched glass As the sun penetrates the building a shadow is cast from the gnomon onto the 1 inch thick laminated glass which has hour lines etched into its surface. The time is viewed from the underside of the dial. A deep carved mountain landscape is artificially lighted in the lower section.
Nashville Tennessee USA Equatorial Dial 853
The equatorial dial made of aluminum operates on a unique principle. The equatorial time ring is allowed to rotate. Fixed to its co-rotating noon hour meridian ring is a plate with the analemma, extending +/- 23.5 deg from the equator. At top of the equatorial ring is a small hole allowing sunlight to make a spot on the analemma plate. The whole assembly is rotated until the sunlight spot falls on the analemma (with monthly marks to avoid ambiguity). One tells time using 5-minute time marks on the top of the equatorial ring read by one of two indicators either as central standard or daylight savings time.
Nashville Tennessee USA Vertical Dial 425
A 6 x 7 foot vertical dial declining 16.4? east of south sits above the entrance to the Science Building. The dial shows hour lines, declination lines and a noon analemma.
Nashville Tennessee USA Analemmatic Dial 766
A 16 x 12 foot analemmatic dial placed in the Experience Center of the 200 acre Ellington Agricultural Center. Dial is built of paver stones flush to the surroundings with painted inset circular hour marker paver stones and rectangular paver stones for the central date line. Directions for use are painted on the date line.
