The origin of Prague goes back to the 7th century and the Slavic princess Libuše, a woman of great beauty and wisdom who possessed prophetic powers. Libuše and her husband, prince Přemysl, ruled peacefully over the Czech lands from the hill of Vyšehrad. A legend says that one day Libuše had a vision. She stood on a cliff overlooking the Vltava, pointed to a forested hill across the river, and proclaimed: "I see a great city whose glory will touch the stars." ("Vidím město veliké, jehož sláva hvězd se dotýkati bude."). She instructed her people to go and build a castle where a man was building the threshold (in Czech práh) of a house. "And because even the great noblemen must bow low before a threshold, you shall give it the name Praha". Her words were obeyed and some two hundred years later, the city of Prague became the seat of the Premyslid dynasty.
