About this item

  • LUMIBRICKS: In a world full of building block brands, LUMIBRICKS stands apart—bringing not just creativity, but warmth and light to every build. We believe building blocks are more than a pastime. They are a way to express love, spark emotion, and capture moments.
  • More Than Just a Building Set: This architectural set features our exclusive lighting system: 16 strategically placed LED light points (Batteries Not Included). With a toggle switch, the light shines through the three colored brick windows of the treasury, refracting into blended colors. Both the exterior and interior of the treasury can be illuminated, giving you an immersive experience in the dark. The set includes 20 printed pieces, saving you the trouble of applying stickers.
  • Two-layer structure above and below ground: The entire set can be divided into two parts: above ground and below ground, including 6 detachable modules and 7 movable mechanisms. The above-ground part includes: the treasury hall, throne area, tower, and aerial corridor (connecting to the banquet hall). The below-ground part includes: the treasure room, fireplace secret area, secret passage, viper room, and hidden sliding door.
  • Medieval Atmosphere: We strive to recreate medieval architectural craftsmanship, combining functionality and decoration, reflected in flying buttresses, pointed arches, ribbed vaults, multi-colored windows, and more. The building's exterior features an L-shaped structure, the highest spire, stained glass rose windows, red roofs, thick stone walls, and gold decorations, collectively presenting an architectural image that aligns with medieval memories, meeting collection and display needs.
  • Medieval Storytelling Ready: 5 minifigures with different identities dressed in unique costumes: 1 king, 1 treasury steward, 1 exotic envoy, 1 guard, and 1 thief attempting to infiltrate the treasury (plus a maid outfit). This set can be perfectly combined with the L9071 Banquet Hall to help you act out your own storyline.
