Established in 1999 at Ražinskas’ homestead, the museum was later relocated to Kaunas before returning to Upninkai in 2018 after privatization. The exhibits include a variety of historical geodetic instruments, such as leveling devices, theodolites, tacheometers, rangefinders, a plane table, measuring tools, map-drawing and calculation instruments, and even a camera used for aerial photography.
The museum stands out for its collection of unique devices, such as a German-made bubble level examiner and a 1932 planimeter. The exhibition also features a series of maps showcasing the evolution of cartography from the 16th to the 21st century. By prior arrangement with the exhibit caretaker, visitors can hear fascinating stories about land surveying, the measurements of the Struve Geodetic Arc, and other highlights of geodesy.
