Czechia.

Prague's Old Town Hall combines the astronomical clock on its square-facing exterior with a historic tower. The two experiences require different amounts of time.

The clock draws attention from Old Town Square, but an ascent of the tower changes the visit into a city viewpoint. Decide which experience you want before joining a queue or buying entry. The building makes more sense when seen in relation to the square around it, not as an isolated facade.

Decide whether to see the clock from the square or enter the tower for the view.
