The Timewheel in ‘Procession Sq’, on the park’s western edge, is the world’s largest hourglass, standing 8m high and weighing 60 tonnes. Unveiled on 1 May 2004 to commemorate Hungary’s entry into the EU, it unfortunately no longer functions; when it did the ‘sand’ (actually glass granules) flowed from the upper to the lower chamber for one year, finishing exactly at midnight on New Year’s Eve, when the wheel was reset to begin its annual flow.

Provocatively, the Timewheel stands a short distance from the parade grounds of Dózsa György út, where communist honchos once stood to watch May Day processions and where the 25m-tall statue of Joseph Stalin was pulled down by demonstrators on the first night of the 1956 Uprising.
