The Queens county seat of Jamaica is also one of the borough's five official towns and postal designations.  This historically rich area was home to the first church built in Queens in 1662, which is also the oldest Presbyterian church in the nation.  Although the county offices are headquartered in Jamaica, the borough hall and related offices are located in Kew Gardens.  Transportation has always played a major role in this area, beginning with a toll road between Hempstead and the ferry in Brooklyn, now Jamaica Avenue, that emerged as a center of commerce.  The Long Island Rail Road attracted more industry to the area, and John F. Kennedy International Airport is located within its boundaries.  Today's downtown district is undergoing revitalization as shopping center and hub of governmental offices.
