Why is the Astronomical Clock The Biggest European Masterpiece? 🇪🇺👑 It was built in 1410 — and 70% of its mechanism is still original. Through its dials, you can read 3 different times at once: Old Czech time, Central European time, Babylonian hours, even the zodiac. The Sun shows the season and time of day. The Moon shows its current phase. And every hour, the clock plays its famous show. #prague #europetravel #traveltiktok
