How high is Signal de Botrange, the highest point in Belgium?

Signal de Botrange is the highest point in Belgium, located in the High Fens (Hautes Fagnes in French, Hoge Venen in Dutch, Hohes Venn in German), at 694 metres (2,277 ft). It is the top of a broad plateau and a road crosses the summit, passing an adjacent café. In 1923, the 6 m Baltia tower was built on the summit to allow visitors to reach an altitude of 700 m. A stone tower built in 1934 reaches 718 m.

For several decades a meteorological station was installed at signal Botrange. Since 1999, it was replaced by an automatic station of the Royal Meteorological Institute of Belgium installed on Mount Rigi (scientific station of the High Fens - University of Liege), which is between the signal and the house Botrange Michel.

Signal de Botrange experiences stronger winds than the centre of Belgium. Average and extreme temperatures are usually lower than at any other place in Belgium: the minimum temperature recorded (-25.6 °C) does not, however, exceed the absolute record (-30.1 °C), observed in the valley of the Lomme, at Rochefort during a temperature inversion. In winter, for three months, on average, the average temperature remains below 0 °C.
