What Makes this set WOW?

Removable Interior Panels: A unique feature that allows the rear of the National Gallery to be removed, revealing a miniature art gallery with block paintings and sculpture.

Iconic vehicles of London: The model includes four micro-vehicles - two famous red double-decker buses and two black taxis, which give the model dynamism and realism.

Precise details of the square: The set faithfully reproduces Nelson's Column with a nanofigure on the top, four lions at its base and fountains made of translucent elements.

Advanced landscaping: Innovative techniques were used to build a multi-level base, including stairs made of sandwich panels and roads mounted at an angle using hinges.
