Timewheel - Olof Palme sétány 3 Budapest, Hungary

The Timewheel in Budapest is likely the largest hourglass in the world. It takes the whole year to completely drain and only needs resetting on New Year’s Eve. The monument was created to commemorate Hungary’s addition to the European Union in 2004. Time is measured with tiny pieces of glass which pass through the clock. A computer system is used to keep the timing right.
