- Location:
- A vertical sundial located on the south wall of Mullanphy Elementary School,St. Louis, one block East of the Missouri Botanical Garden. Visible from the street if you look to the right on the stonework near the roof line. A large tree blocks the best view and shades the sundial during a large portion of the day.
- Description:
- The Mullanphy School is the last school of 48 designed by and constructed under the guidance of William B. Ittner (1864-1936), an architect and Commissioner of School Buildings for St. Louis, MO. Only hour lines are marked on this simple vertical sundial. The picture of the sundial was taken at 1:41 PM CDT on 7 May 2019. Using the relation T(solar) = T(civil) + EOT - Daylight - LonCorrection, with EOT=3.3m, Daylight=1h, and LonCorrection=1m, indicates that the dial should show 12:43:31. This suggests that Ittner’s sundial at the Mullanphy School displays this sundial time to a reasonable approximation, especially considering that its only time markings are hour lines.
