4. Tower Bridge 10214

The Lego Creator Expert model has 4295 pieces and is suitable for ages 16+. The Tower Bridge 10214 set perfectly depicts the original architectural summary of London. To build the miniature set of the world-famous structure, you must add the suspensions by fitting tiny pieces together, and the towers on top of each bastion require skill to be attached correctly so that the height of both bastions remains the same. This timeless London landmark on the River Thames has enchanted locals and tourists alike since 1894 - it takes advanced building techniques to recreate its magic.

Highlights:The most complicated part of the set is the functional drawbridge, which can be opened like the original Tower Bridge to let cargo ships pass. Several rare parts and bricks in rare colors are added in this model, which may make you feel unfamiliar with the building process if you don't follow the building instructions.

• Featuring four miniature vehicles, namely the red London double-decker bus, the green car, the yellow truck and the black cab, the bridge takes you back to the streets of London but requires skill to ensure the bridge remains stable.
