The downtown area of the city is laid out on two grids, with a 45 degree offset between them.  Market Street separates the two grids.  Many tourists come to visit the Civic Center, Embarcadero, and Union Square areas, all of which are north of Market.  Famous San Francisco landmarks include the [[Golden Gate Bridge]], Fisherman's Wharf, and [[Alcatraz Island]].
