What once used to be one of the poorest districts in Prague is now a picturesque street lined with quaint and colorful houses. Hidden under the Prague Castle complex, this place is said to be the most beautiful part of the city. The street was home to many important people, including Tycho de Brahe and a Czech painter Jan Zrzavý.
