At Žluté lázně, the Royal Route from Prague Castle to Karlštejn via Krteň brings to life a king and his times. It reveals the dreams and plans of Charles IV and explains, in the most enjoyable way, the reasons for his fame and greatness. Highlights include Charles Bridge, Karlštejn, the crown jewels and more. Anyone can follow in the footsteps of Charles IV. From the bank of the Vltava you step through a gate into medieval Prague. The illuminated story of Charles IV leads from the glowing Charles Bridge past the royal crown to the golden spires of the Gothic city — every stop a chapter of its own: king, builder, emperor. Thousands of LED lights and welded sculptures trace the coronation jewels, cathedral arches and legends of the imperial court.
