This model is designed and authorized by Sir Perceval. It includes both the MOC-207737 Castle Hohengeroldseck Part 1 and MOC-208147 Landscape Expansion 1. The complete Castle Hohengeroldseck is composed of 62 individual modules, totaling an incredible 132,265 pieces when fully built. The final dimensions of the full castle are approximately L349.9cm x W121.1cm x H67.4cm.

Castle Hohengeroldseck is now just a ruin, but the designer, Sir Perceval, has set himself the goal of creating a reconstruction that is as authentic as possible in  miniature scale. He worked with historical plans and studied the remains of the castle on site in great detail. He also used a reconstruction drawing as a key reference. The build will be completed in several stages, with the castle area divided into four construction phases. So far, only Part 1 has been completed, while the remaining sections are still in the planning stage. Part 1 has been designed to stand on its own as a self-contained display model, even without the other parts.

Part 1 includes some landscape in front of the castle, sections of the ring wall, the entrance gates, and a stable/storage building with an inner courtyard. Part 2 will add more ring walls, the smithy, and another building. Part 3 will complete the ring wall with a larger tower. Finally, Part 4 will feature the main castle, which will also be designed as an independent, exhibit-ready piece.

Castle Part 1 comprises 37 modules: Modules A 1–7, B 1–7, C 1–7, D 1–7, and Building 1–9. In addition to the castle, Sir Perceval has also planned a landscape that can be expanded in the future. At present, there is Landscape Expansion 1, which includes an additional 25 modules: A 8–13, B 8–13, C 8–13, D 8–13, and Building 10.

Together, Castle Part 1 and Landscape Expansion 1 include a total of 62 modules. This bundle contains both Castle Part 1 and Landscape Expansion 1.
