Kampa Island near Charles Bridge is one of the most delightful places in Prague, with picturesque houses and a tranquil waterside park. It is a good place to spend an evening walking by the river Vltava and enjoying the special atmosphere of the place. Kampa Island is separated from Prague Lesser Town by the river arm Devil´s Stream. It is probably named after the house “At the Seven Devils” nearby. There is a particularly attractive part of Kampa with houses standing right by the river. It is nicknamed The Venice of Prague. Until the 16 th century, there were only mills and gardens at the Kampa Island. It was often threatened by floods. Four mills are still preserved there, the biggest mill-wheel being eight meters large in diameter.
