Picoto da Melriça is a monument and the geodesic centre of mainland Portugal. Constructed in 1802, the triangulation station sits on top of the Serra da Melriça, a high mountain range in the municipality of Vila de Rei, offering a 360° view of its surroundings. Despite being the geodesic centre, it is not the geometric centre of mainland Portugal, which is located in the neighboring Mação. Read more on Wikipedia
