The cheapest shore fortification that can be built are the Mounted Guns, a pair of small-caliber cannon on a stone platform. While they lack the range and punch of a Cannon Tower, Mounted Guns have an additional benefit: ships hit by their shot are slowed, making it more difficult for them to escape the guns' range. As such, mixing a set of Mounted Guns into just about any harbor fortification can be a good idea.
