||Mina Salman Port
||Manama (Al Manamah), the capital, is located on the northeastern tip of the island of Bahrain. The main port, Mina Salman, also is located on the island, as are the major petroleum refining facilities and commercial centers. Causeways and bridges connect Bahrain to adjacent islands and the mainland of Saudi Arabia. The oldest causeway, originally constructed in 1929, links Bahrain to Al Muharraq, the second largest island. Although the island is only six kilometers long, the country's second largest city, Al Muharraq, and the international airport are located there. A causeway also connects Al Muharraq to the tiny island of Jazirat al Azl, the site of a major ship-repair and dry-dock center. South of Jazirat al Azl, the island of Sitrah, site of the oil export terminal, is linked to Bahrain by a bridge that spans the narrow channel separating the two islands. The causeway to the island of Umm an Nasan, off the west coast of Bahrain, continues on to the Saudi mainland town of Al Khubar. Umm an Nasan is the private property of the amir and the site of his personal game preserve.
