The scan was supplied as a GLB (photogrammetry with four texture atlases). The mesh was not rebuilt. Studio lighting and a charcoal cyclorama were added; the original unlit scan materials were converted to Principled BSDF so the stone and tile textures pick up studio light. 144 turntable frames were rendered in Blender Cycles at 1600×900, 128 samples with adaptive sampling (threshold 0.01, minimum 32) and OpenImageDenoise, from an elevated three-quarter camera about 22 degrees downward.

This is an illustrative 3D model for a frame-based viewer. It is a photogrammetry scan and shows some capture artefacts (for example roof tarps and incomplete paving at the edges). It is not an official government or church asset.
