Letenský zámeček is a restaurant located in the heart of Letná Park (Letenské sady), a large park built on a plateau above steep embankments along the Vltava River with wonderful views over the Old Town of Prague. The history of the building starts back to the mid-19th century when the Town of Prague purchased an old church vineyard on the slopes of Letná and founded a park there for the citizens of Prague to walk and relax during the spare time. A restaurant, designed by the Czech architect Vojtěch Ignáce Ullmann, was built in 1863 above the historic center of Prague, to ensure the citizens a place where to get refreshment. Today four restaurants of differing styles serving dishes from Czech and international cuisine are in the building.
