I have read about this wheel in a review of what to see with kids in Budapest. Thanks to authors for explanations where to find it. If I had no referent points, we easily miss it.
The concept reminds me the sphere on a Time’s Square in New York. But this wheel is a sand clock for a whole year!...
Apparently given the Budapest people for joining the European Union. Also it appears to be expensive to maintain by the government. Nevertheless the city touts it as an attraction. An attraction for the tourists. Maybe time better spent on other cultural pieces, of which there are many, in Budapest.
Nice sculptured one-year timewheel, situated at the southern edge of Budapest's City Park. I missed an explanatory sign describing the background and purpose of this, but a Wikipedia search provided the necessary information.
Unfortunately the lower glass pane on the one side was cracked when we visited, but this didn't detract from the overall impression.
