A Heliport is by definition an area of land, water, or structure used or intended to be used for the landing and takeoff of helicopters, and includes its buildings and facilities (if any). In other words, it is a small airport suitable for use by helicopters and some other vertical lift platforms. Designated heliports typically contain one or more touchdown and liftoff area and may also have limited facilities such as fuel or hangars. In some larger towns and cities, customs facilities may also be available.

Early advocates of helicopters hoped that heliports would become widespread, but they have become contentious in urban areas due to the excessive noise caused by helicopter traffic. (source)
