Prague Castle is a large castle complex on a hill in Prague, where visitors can see St. Vitus Cathedral and Golden Lane together. The interior of St. Vitus Cathedral, the small shops of Golden Lane, and the view of red roofs and the Vltava River from the South Gardens are the main features. Inside the castle, historical explanations help the architecture and decorations make more sense, and St. Vitus Cathedral is still a space in use. Walking through the castle in a zigzag pattern requires a lot of walking, so comfortable shoes are needed.
