 Western Main Road, the area's major thoroughfare, has long been the city's main nightlife district, sometimes nicknamed "the city that never sleeps".Long Circular Road, which curves north from Western Main Road then east to meet Maraval Road, forms part of the city boundary.Its "circle" encloses Flagstaff Hill, a small rise with the US ambassador's residence at its summit, which lends its name to an area of apartment buildings at its southern foot.
