Monument to the Sun or The Greeting to the Sun is an interesting monument in Zadar, Croatia, dedicated to the Sun. Monument consists of 300 multi-layered glass plates placed on the same level with the stone-paved waterfront in the shape of a 22-meter diameter circle. Lighting elements installed in a circle turn on at night, and produce show of light. Monument symbolizes communication with nature, with the aim to communicate with light, while the nearby Sea organ represent aim to communicate with sound. On the chrome ring that surrounds the photo-voltage solar modules on the Sun, are inscribed the names of all of the saints after which present and previous churches on the Zadar peninsula have been named. Next to their names and the date of their feast are the declination and the altitude of the Sun north or south of the equator (DEC minimum of -23 degrees to a maximum of 23 degrees), the length of the sunlight in the meridian on that day, and in that place on the waterfront, which makes this Monument kind of a calendar.
