The capital of The Bahamas, Nassau, stands on New Providence Island. In the capital, tourists can shop in the bustling ‘straw market’, where local vendors create unique straw goods on the spot, or the more sophisticated shops in Bay Street. The 18th-century Fort Charlotte on West Bay Street has a moat, open battlements, dungeons and a magnificent view of the harbor. The nearby Ardastra Gardens have tropical flowers and pink flamingos. The Queen’s Staircase, at the top of Elizabeth Avenue, is a 40m- (102ft-) climb up steps carved into the limestone leading to Fort Fincastle and the Water Tower. Built in 1793, Fort Fincastle is in the shape of a ship’s bow. The Water Tower is the highest point on the island, 85m (216ft) above sea level. An elevator takes visitors to an observation deck for panoramic views. Many bars, restaurants and discos can be found along Cable Beach, a 2.5 mile-long stretch of golden sand, located just 3 miles outside the city. Paradise Island boasts some beautiful beaches, a 14-acre aquarium, 34 acres of beautiful landscaped gardens, the Caribbean's largest casino and a multitude of resorts. Sunbathing, diving, fishing and boating are the main daytime amusements on these islands. The Bahamas National Trust is based here.
