>>11321440Not a Western fort but there's a modular castle currently on the market that comes in various sets; some have enough parts for a modest complete castle, others one or more of the towers and/or wall pieces and other stuff, another adds turret pieces for the towers. Bought enough sets to make a fairly grand fortress, might get one or more additional sets in the future for even larger setups.
Can be a challenge to assemble the towers cuz of less than stellar quality control and the wall pieces can't connect together without a tower but overall it's a great and fairly cheap way to have an army men castle. The sets tend to include at least a handful of knights and men-at-arms, sometimes mounted ones, usually some scenery pieces, siege engines, some even include a couple dragons or pirates and skeletons or a bunch of 1/72 knights, oddly.
