Vinohradská vodárna

This guide to the Vinohradska vodarna in Prague explains why an 1882 water-pumping station was built to look like a fairy-tale castle, complete with four stone angels holding clocks at its corners. It traces architect Antonin Turek's design and the steam engines hidden inside, hauling river water up to a rooftop tank that then fed the neighborhoods of Zizkov and Vrsovice by gravity alone. Look up at the angels as you listen for the hour.
