After the gate was done, I added a ship and eye-candy. Midgard Eagle
This is an Enlighs medieval dry dock big enough for one ship. It comes with some (port/maintenance) buildings, crates, workers, and other eye-candy, and the gates of the dry dock can be closed.
To make this dry dock, I first made a narrow inlet by playing around with elevation. Then I placed two gates on either side of the inlet and placed a soldier, shrinked so that they would not be visible, close enough to the gates to make them stay open. When they opened, the opened gate door covered the opening of the dry dock.
After I had finished the dry dock I realised that the opening apparently isn't big enough for ships to pass trough. I daresay it still might look good in scenarios, though.
. I just added the objectives and the damaged ship to give you an impression of what you can do with the Dry Dock.
