The town grew up around a 12th Century Royal castle, of which the surviving 90 ft high Keep dominates the surroundings of Orford to this day. Henry II built the castle for coastal defences and against invaders from the sea, underlining the political and commercial importance of the area at that time. However, it still has its areas of importance and it is still a beautiful and relaxing area to visit.
Cruises run for anything from one to four hours with meals available on some trips.
