Blagoveshchenskaya Church, or "Church of the Annunciation of the Blessed Virgin", in the village of Pokcha, is a monumental site developed during several historical phases in Cherdyn district, in Upper Kama (Russia). The original wooden complex was replaced in 1785 with a new one in stone and brick masonry, divided into several blocks: the main block, with a quadrilateral plan, defined a nucleus for the refectory, the chapels of St. George (south) and St. Nicholas (north), the bell tower and the entrance narthex. In 1910, a reconstruction intervention modified large portions, in particular the bell tower, completely replaced, and the central vault and apse; the interiors are preserved, with paintings and ornaments from 1870.
The general coating of the building was integrated by an additional external brick layer with a decorative function.
The first restoration works began in 1920, until it was completely abandoned in 1940 and converted into an energy central: in the 1990s the central vault and roof of the bell tower partially collapsed, after repeated flashes attracted by the electrical system. Due to the extensive damage, the church is excluded from the local list of architectural monuments of interest, preventing any new intervention and restoration initiatives and leaving the site to ruins.

The on-site documentation campaign, conducted in 2018, has been organized on a double level of acquisition, static from the ground with Terrestrial Laser Scanner (TLS) and aerial with drones for 3D photogrammetry (UAV).
The TLS measurement, with a FARO Focus S150 instrument, produced 64 scans with the combined use of the internal photographic camera, developing a point cloud of 298,598,962 points, each one with specific RGB values. The UAV survey, essential for the reliable documentation of the elevated portions of coverage, was conducted with a DJI Phantom Pro drone, producing 207 photographic shots through a "point of interest" flight plan around the monument. The photographic campaign was integrated with a ground shooting, through a Nikon D7200 camera, collecting an overall photographic archive of 5,601 photographs. The fast survey was completed with the acquisition of 360° spherical photographs and videos through a Ricoh camera, also contributing to the documentation of the rural settlement and landscape context.
From the integrated terrestrial and aerial database, 2D vector drawings were produced for the description of the monumental portions of ruins; ”reality-based” 3D mesh models were also produced for the evaluation of the state of conservation and structural instability of the complex, in particular of the central vault portion.
