The gatehouse and barbican for my modular castle MOC, Castle Peregrine.
About this creation
The gatehouse was the first part of Castle Peregrine that I designed. I wanted to build a multi-levelled gatehouse centered around an area guarded by twin portcullises and attacked by arrow slits and murder holes. The portcullises travel up and down in 1-wide grooves and are controlled by winches. The backs of the towers are hinged open to allow access to the interior. The gatehouse openings are designed to connect to wall segments.
I designed the gatehouse first with the intention of having the forebuilding on it. I was never wholly pleased with the results for two main reasons. The passageway through the gatehouse is only 6 studs wide (under a 1 x 8 x 2 arch) and the travel path for the portcullis precludes any bridge raising chains or strings that are even with the end of a bridge.
Those considerations made me decide to add a separate barbican module. The barbican almost seemed to design itself--I was surprised at how quickly it came together. The first cut looked too high when paired with the gatehouse. I reduced it by 4 brick heights, and it provided a good facade while not obscuring the gatehouse.
I really like the design and technical aspects of this. I am working on a similar although much smaller barbican based on one at Krakow. Your documentation and detail has been helpful. Awesome build. A++!
