Signal de Botrange
Signal de Botrange is the highest point in Belgium, reaching an elevation of 694 meters, and is situated on the High Fens (Hautes Fagnes) plateau. This extensive nature reserve is characterized by its unique raised bog landscape, which is among the oldest and most ecologically valuable in Northwestern Europe. Geologically, the substrate consists of Cambrian sediments shaped by erosion over millions of years. To reach the symbolic height of 700 meters, the Baltia Tower was constructed in 1923, consisting of an artificial mound with a stone staircase. The climate at Signal de Botrange is significantly harsher than the rest of the country, featuring frequent fog, high precipitation, and prolonged snow periods in winter. Since 1957, the area has been under strict nature protection to preserve delicate flora such as cottongrass and various peat moss species. The region also serves as a major watershed for the area's rivers and provides hikers a wide network of wooden boardwalks that allow for navigation through the marshy terrain. Scientific monitoring of meteorological conditions has been conducted here for decades via a permanent weather station.
