The primary objective of our research approach is to produce the 3D geometry of the monument known as “Metochi of Agia Anastasia in Kritsiana of Epanomi”. After the presentation of significant historical data, a more comprehensive examination follows, which includes the use of modern 3D documentation techniques employing two different kinds of laser scanners—a Terrestrial Laser Scanner (TLS) and a Simultaneous Localization and Mapping (SLAM) instrument. The geometric accuracy of the two independent point clouds that are produced is evaluated in order to derive certain conclusions. By utilizing the final measurements and digitization method, a surveying plan in 1:200 scale and a set of eight final drafting designs at a scale of 1:50 were produced. The drafting designs are compared to those from an earlier documentation performed in 2001 using traditional Surveying Engineering Methods and instruments (Total Station). The objective is to draw conclusions concerning the precision of the produced printed reproduction of the monument’s documentation and estimate errors that occurred during the creation of drawing maps on paper. Finally, our study investigates the process of constructing a 3D physical model of the monument at scale 1:200, utilizing a modern 3D printing system.
