Some sources say that the creek extended as far inland as Al Ain, and that the Ancient Greeks called it "River Zara." Historically, the creek divided the city into two main sections – Deira and Bur Dubai. It was along the Bur Dubai creek area that members of the Bani Yas tribe first settled in the 19th century, establishing the Al Maktoum dynasty in the city. In the early 20th century, the creek, though incapable then of supporting large scale transportation, served as a minor port for dhows coming as far away as India or East Africa. Although it impeded the entry of ships due to current flow, the creek remained an important element in establishing the commercial position of Dubai, being the only port or harbour in the city. Dubai's pearling industry, which formed the main sector of the city's economy, was based primarily on expeditions in the creek, prior to the invention of cultured pearls in the 1930s. The area is known as Al Fahidi Neighbourhood or old Dubai. The construction of Al Bastakiya dates back to the 1890s. In its prime, the locality was capable of supporting 60 housing units, most of which were separated by narrow, winding lanes. Meydan Racecourse is a horse racing facility located in Dubai, United Arab Emirates. It opened on 27 March 2010, replacing Nad Al Sheba Racecourse, which formerly occupied the same site. It can accommodate over 60,000 spectators in a 1-mile-long grandstand. When not used for races it will serve as a business and conference integrated facility. A horse racing museum and gallery are also planned. The development also includes a nine-hole golf course. The Meydan Racecourse includes Meydan Marina, The Meydan – the world's first five-star track-side hotel with 285 rooms, two race tracks and the Grandstand, which comprises a hotel, restaurants, a racing museum and 72 corporate suites for entertaining throughout the year. It has a 2,400 metre left-handed turf race track and a left-handed 8.75-furlong (1,750 metres) Tapeta synthetic dirt course. It operates from November through March and features the Winter Racing Challenge, Dubai International Racing Carnival and the Dubai World Cup Night. The Dubai World Cup is the world's richest race day with over US$26.25 million in prize money. The Racecourse district occupies 67 million square feet (620 ha); the overall Meydan City development however is 200 million square feet (1,900 ha).
