Coastal (Civ4)

Amsterdam, the Dutch capital, is a coastal city that owns many profitable water tiles.

In Civilization IV, a coastal tile is a land tile that is directly adjacent to one or more coast tiles.

A coastal city is a city founded on a coastal tile. All naval units and the following buildings and wonders can be built only in coastal cities:

• Customs House
  • Feitoria
• Dike (Also allows Riverside cities)
• Drydock
• Harbor
  • Cothon
• Lighthouse
  • Trading Post
• The Colossus
• The Great Lighthouse
• Moai Statues

Most coastal buildings require the city be adjacent to a body of water containing at least 10 tiles. The Drydock and production of most units requires adjacency to a body of water with at least 20 tiles. Work Boats may be built in coastal cities on smaller bodies of water if (and only if) a relevant resource is present.

In addition, coastal cities and forts are considered ports, where the following rules apply:

• Friendly naval units can move into the city/fort.
• Enemy naval units cannot move there.
• Units in the city/fort can load and unload from naval transports without losing movement.
