Port Elizabeth, on the shores of Algoa Bay, also known as the 'Friendly City' ( PE is genuinely a friendly place) is the largest coastal city between Cape Town and Durban and has the third largest port in South Africa. Port Elizabeth and its nearby sister city of Uitenhage, are the main centres for South Africa's car Industry. The actual founding of Port Elizabeth dates back to the arrival by sea of 4 000 British Settlers in 1820 to become the first permanent British Settlers in the country. Port Elizabeth is considered to be the country's leading centre of Art Nouveau style architecture. Many buildings display the intricate stonework, wrought iron and stained glass of that era and are very visible in the historical areas of the city. Bayworld, one of Port Elizabeth's major attractions and comprises the Museum, Oceanarium, Snake park, Tropical House and No. 7 Castle Hill Museum. The Main Museum of Bayworld blends cultural and natural history. The Oceanarium with its popular dolphin and seal presentations take place at 11:00 and 15:00 daily. Within the Oceanarium is a good aquarium including 2 larger tanks housing sharks. No 7 Castle Hill Museum is one of the oldest surviving settler cottages and dates back to 1827. The house has been painstakingly restored to reflect the history and lifestyle of earlier days. Fort Frederick, on Belmont Terrace, overlooking the Baakens River, was built in 1799. Donkin Street and Reserve are immediately behind the town centre. The reserve is flanked by some fine examples of Victorian architecture.
