History
Signal de Botrange became Belgium's highest point following the annexation of the Eastern Cantons in 1919, surpassing Baraque Michel.
In 1923, the 6-meter Baltia observation tower was constructed to allow visitors to reach an altitude of 700 meters.
Later, in 1933-34, a stone tower crowned with a steel weather vane was built by François Fagnoul.
Over time, the site evolved to include a 50-meter data relay tower installed in 2013 to facilitate real-time financial data transmission between London and Frankfurt.
The meteorological station originally located here was replaced in 1999 by an automatic station on Mount Rigi nearby.
