Continuing your sightseeing cruise upstream takes you to this panoramic view of Old Town (Staré Město). Clustered at the eastern entrance to the famous Charles Bridge are three landmarks: the large dome of Church of St. Francis of Assisi, the Old Town Bridge Tower and the smaller dome of St. Salvator Church. To the right of them is the dramatic tower of the Old Town Waterworks. Several operators offer sightseeing trips along the Vltava river, ranging from one-hour excursions to dinner packages. Prague is also a popular port-of-call for seven day cruises connecting with Vienna, Budapest and Bucharest or 14 day itineraries with a terminus in Amsterdam.
