This is the world’s largest hourglass.

Unveiled on May 1st 2004 to commemorate Hungary’s entrance in the European Union, The Time Wheel is made out of red granite, steel and bullet-proof glass and it combines one of humanity’s most primitive time measuring devices with a very precise computer. It lies in Budapest near the entrance to City Park. The sand in the hourglass flows from one side of the device to the other for an entire year and the last grains are programmed to flow exactly at midnight on New Year’s Eve. The flow is then turned manually so that it can start measuring time for another year. It takes 45 minutes for 4 people to turn it 180 degrees using metal cables.

The Time Wheel hourglass was designed by Istvan Janaki.
