Morocco's capital, Rabat is a modern city with wide boulevards, gardens and light, white buildings, for the most part a far cry from the hectic warrens of the other Imperial cities of Marrakech and Fez, but no less steeped in history with its origins going back to the 7th century. The King of Morocco lives here in his palace amid trees and flowers. Being an administrative capital the city is somewhat conservative and serious, but there is some local colour to be found in the old part of the city, the Medina, and the Kasbah. Recreational opportunities abound too, with a world-renowned golf course (the Dar Es Salaam Course) and a few lovely beaches at hand. Rabat sits on the Atlantic coastal plain at the mouth of the river Bou Regreg, opposite to its twin city of Sale.
