The Solar Hour Benches are a set of six oval benches, each with a slit aperture aligned with the sun for one particular hour: 10:00 a.m., 11:00 a.m., noon, 1:00 p.m., 2:00 p.m. or 3:00 p.m. solar time. Throughout the year, for only twenty minutes before and after the corresponding hour, sunlight travels through the aperture and projects onto inscriptions on the ground. Scientific and cultural aspects of time and sundials are also depicted on each bench.
