Description:
  • This is a south facing reclining vertical sundial made of stone about one and a half meter square. The dial's concrete mount adjusts the dial to true south even though the carillon tower is not N-S aligned. Hour lines and Roman numbers on the dial go from 7am to 5pm. Monthly declination lines show the date as well as the solstices and equinox. A simple rod gnomon exits a gold ball at the top of the dial. The dial itself is well above eye level and hard to read. The other end of the carillon tower has an Aztec calendar.
