I built a Claude Code skill that reconstructs historical monuments in 3D, stone by stone

Description and use

A Claude Code skill that automatically researches, measures, phases, and procedurally generates 3D reconstructions of historical monuments, with interactive timelines, using Three.js. Examples include the Leaning Tower of Pisa, Eiffel Tower, and Colosseum.

Problem

Users want accurate, phased 3D reconstructions of historical monuments with sourced construction dates and dimensions, rather than generic AI-generated models.

Outcome

The skill produces interactive 3D reconstructions of monuments such as Leaning Tower of Pisa, Eiffel Tower, and Colosseum, with phased, dated, and sourced construction details.

Workflow

• 1. User invokes /monument with monument name
• 2. Skill researches historical sources
• 3. Extracts footprint and architectural dimensions
• 4. Identifies construction phases
• 5. Generates procedural 3D geometry with Three.js
• 6. Builds interactive timeline of construction
• 7. Compares model to reference photographs to refine accuracy

Evidence

The idea is simple: give Claude Code the name of a historical building, and it researches its history, reconstructs its architecture, and generates an interactive 3D model showing how it was built over time.

Source

The entire experience runs locally using Three.js.

Source

One limitation worth mentioning: detailed reconstructions can take 30–90 minutes, and the first result often needs refinement.
