Golden Lane is a street situated in Prague Castle, Czech Republic. Originally built in the 16th century, to house Rudolf II's castle guards, it takes its name from the goldsmiths that lived there in the 17th century. Although the lane was temporarily called the Street of Alchemists or Alchemists' Alley, alchemists have never worked or lived there. Golden Lane consists of small houses, painted in bright colours in the 1950s.
