Grand Priory Square (Velkopřevorské náměstí) leads across a bridge to tiny Kampa Island. Kampa Island, isolated from Lesser Town by a side channel of the Vltava called Devil’s Stream (Čertovka), is an unexpectedly peaceful part of Prague. There are picturesque little houses and a still functional mill. Worth visiting is also a place called Sovas’ Mills (Sovovy mlýny), which houses an exquisite collection of modern art.
Here you find Lennon Wall. Lennon Wall was an ordinary wall in Prague, but since John Lennon’s death, Prague’s youth have covered it with John Lennon inspired graffiti and Beatles lyrics.
