Výstaviště is what's left of the moment Prague threw itself a party. The grounds were built for the 1891 Jubilee Exhibition, and the great iron palace at the centre has been hosting fairs, concerts and ice hockey ever since — a Victorian fairground that never quite stopped running. Three flat kilometres, heavy on iron and glass.
Start at the Výstaviště tram and walk straight in to the Průmyslový palác, the Industrial Palace: 1891, a riveted cathedral of arches and a central clock tower, the left wing rebuilt after a 2008 fire. Stand well back to take the whole span. Behind it sits the Křížíkova fontána, the musical fountain, named for the engineer who first lit the city — quiet by day, a light show after dark in season.
Then the two oddities that make the walk. The Lapidárium holds the real stone saints lifted off Charles Bridge for safekeeping, almost always empty. The Maroldovo panorama wraps you inside a single huge battle painting from 1898. Slip out into the edge of Stromovka for a last few trees, then back to Nádraží Holešovice for the metro.
