Southampton is England's leading passenger port. It is rich in historic embarkations, from Henry V's fleet bound for France and the battle of Agincourt to the Mayflower, the ill-fated Titanic, and the maiden voyages of the great ocean liners of the 20th century such as the Queen Mary and the Queen Elizabeth 2. Parts of the town center can seem mundane, having been hastily rebuilt after World War II bombing, but bits of the city's history emerge from between modern buildings. The Old Town retains its medieval feel, and some remnants of the old castellated town walls remain. Other attractions include a decent art gallery, extensive parks, and a couple of good museums. The Southampton Boat Show, a 10-day event in mid-September, draws huge crowds.
