The geodetic marker on-site was officially established in 1802 as the primary reference point for Portugal's trigonometric grid.
Geodesy instruments displayed include original theodolites used during the first national cartographic surveys.
The site functions as both a scientific educational center and a landmark of national historical cartography.
The Museu da Geodesia is located in Vila de Rei at the precise Geodetic Center of Portugal, known as the Picoto da Melriça. The museum provides an interactive overview of the historical and technical evolution of geodesy, the science of measuring the Earth's geometric shape and orientation. Visitors can explore the equipment used by 19th-century engineers to map the national territory with high precision. It is situated adjacent to the geodetic marker that has served as the national reference point for cartography since the 19th century. The facility bridges the gap between complex mathematical mapping and practical physical landscape observation.
