Downtown is the central business district of Seattle, Washington. It is fairly compact compared with other city centers on the West Coast of the United States because of its geographical situation. It is hemmed in on the north and east by hills, on the west by Elliott Bay, and on the south by reclaimed land that was once tidal flats. It is bounded on the north by Denny Way, beyond which are Lower Queen Anne (sometimes known as "Uptown"), Seattle Center, and South Lake Union; on the east by Broadway Avenue, beyond which is Capitol Hill to the northeast and the Central District to the east; on the south by Dearborn Avenue, beyond which is Sodo; and on the west by Elliott Bay, which is part of Puget Sound (an inlet of the Pacific Ocean).
