Cologne Cathedral MOC Review: 86,000 Bricks, 1.2m Tall
The Verdict Up Front
This Cologne Cathedral MOC runs on 86,000 bricks, finishes at 1.2 m tall with a 1.5 m base, and the official instructions estimate roughly 220 hours of building. Reference price is around CNY 6,800. The short version: it is the most faithful Gothic cathedral MOC currently available, with both towers, the flying buttresses and the rose window all present and correct. It suits experienced builders with a very large table. Because of the part count and the build time, newcomers should start with the scaled-down version on brickplan.cn first.
1. Exterior Accuracy
The thing that grabs you about the real Cologne Cathedral is the pair of 150 m spires. This MOC builds the two main towers to 45 cm, tapering them course by course with 1x1 bricks and wedge bricks, and tops each one with a cross made from a dedicated moulded piece. The rose window on the front measures 12 cm across and uses transparent bricks in dark blue and dark red to lay out the petal pattern — in sunlight there is no mistaking what it is based on. The west facade's 127 small pinnacles are simplified down to 56 here, but the flying buttress structure is kept complete, which gives the sides a lot of depth.
2. Build Experience and Structure
The instructions break the model into four large modules: tower base, nave, west facade and roof. Local step numbering within each module stays under 50,000, so the sorting workload is manageable. The nave is brick-on-brick construction reinforced with internal shear walls, and the towers get a cross-braced layer every 10 cm, which makes the whole structure very stable. Two things to watch: the joint where the tower top meets the tower body is fixed with technic pins, so lock them in the order the instructions show; and the coloured transparent window bricks are on the soft side, so push them out gently with a brick separator. In testing, a single tower module stripped down in 2 hours, which makes moving it practical.
3. Value and Who It's For
By part count this works out to roughly CNY 0.08 per brick — mid-to-upper range for large architecture MOCs, and about 30% cheaper than a set of comparable size. The real weak points are footprint and weight: the finished model is around 19 kg and needs a surface at least 1.5 m wide. If you love Gothic architecture, have the space, and can live with two or three months of slow, careful work, it is absolutely worth it. If your budget is tight or you want to test the water first, the mini version of the same subject on brickplan.cn is about 12,000 bricks and 38 cm tall for under a fifth of the price.
FAQ
Q: How much does the Cologne Cathedral MOC cost, and is it worth buying?
A: The 86,000-brick version is around CNY 6,800, which is fair for the amount of detail. If you like Gothic architecture and have display space, it is worth it. If money is tight or this is your first large MOC, buy the mini version on brickplan.cn first.
Q: How long does it take to build?
A: The official figure is about 220 hours. At 2 hours a day that is roughly 3 to 4 months. An experienced builder working in long sessions can finish in about 50 days at the fastest, provided the parts are sorted properly.
Q: Can a beginner build this cathedral MOC?
A: Yes, but it is not the place to start. It involves technic pins, wedge bricks and a lot of edge-trim pieces, and beginners tend to get stuck on the tower spire tapering. Finish a church MOC under 5,000 bricks first, then move up.
Q: How big is the finished model — will it fit on a normal desk?
A: It is 1.2 m tall, 1.5 m long and 0.6 m wide, weighing about 19 kg. A normal desk will not take it; you need a dedicated display surface, kept out of direct sunlight so the transparent window bricks do not degrade.
Q: How is it different from the cathedral in official sets?
A: Scale and detail, mainly. This MOC has 86,000 bricks and 45 cm towers with full flying buttresses and rose window. Cathedral models in the official architecture line generally run 2,000 to 4,000 bricks, so height and detail are a whole order of magnitude apart.
