Plymouth, England, a town with a population of approximately 60,400 people, was once one of the most important Royal Navy bases, which made it a prime target of the Luftwaffe during World War II. After the destruction in the blitz of 1941, Plymouth was rebuilt and is now one of the few remaining naval dockyards in Britain. It is also the largest naval base in Western Europe. Attractions include the Royal Citadel, Devonport Dockyard, and the Barbican from where the pilgrims left for the New World in 1620. In 1810, Plymouth was struck by the strongest tornado reported in the United Kingdom. Tourists find Plymouth Hoe, the greens overlooking Plymouth Sound, where it is believed that this is where Sir Francis Drake left prior to setting sail to defeat the Spanish Armada. Festivals held in Plymouth include the British Fireworks Championships, World Championship Powerboat Racing, and Music of the Night--an outdoor production held every two years. Also in Plymouth are theaters, museums, art galleries, and historic buildings. The synagogue on Catherine Street is the oldest Ashkenazi synagogue still standing in the English-speaking world; it was built in 1762. Plymouth is also known for its public parks and sports.
