Heroes' Square
The Timewheel () is a large hourglass, situated in Budapest next to City Park, right of Heroes' Square and behind the Palace of Art ("Műcsarnok"), on the site of a former statue of Lenin that now stands in Memento Park. It is made of granite, steel, and glass, and weighs 60 tons. The "sand" (actually glass granules) flows from the upper to the lower glass chamber for one year.
