The stamp depicts a combined view of two bridges in Prague’s Podoli. The present Stadlec bridge was initially built over the Vltava river nearby Podolsko. The bridge, made of welded iron parts, was built in the Imperial style by Vojtěch Lanna in 1847–1848 and was used for 113 years as part of the major trade route from Bavaria to Galicia. The new Podolsky bridge, made of reinforced concrete, was giant compared to the original chain bridge.
