Recreate the world's greatest landmarks one layer at a time in Monument Builder — a relaxing idle game where history meets construction.

Start with ancient Stonehenge and work your way through the Great Pyramid, the Colosseum, the Eiffel Tower, and the Burj Khalifa. Each monument is built in stages: earn coins by tapping, buy stone, wood, brick, steel, and glass, then unlock technologies from the simple lever to steam engines and 3D printing to speed up your progress.

Research your way through a full tech tree to reduce costs, boost passive income, and unlock new materials. Every completed monument adds real historical facts to your personal collection — learn how the pyramids were built, why the Colosseum could hold 50,000 spectators, and what makes the Burj Khalifa stand 828 meters tall.

Your empire keeps growing even when you are offline. Come back to collect coins earned while away and continue building at your own pace.

Free to play. No ads. No subscriptions. Just monuments, materials, and milestones.
