In 1999 the 21.7-metre-high Kellerberg Observation Tower was built in a modern wood and steel design. The covered tower has a triangular plan and consists of seven larch logs that are connected by metal strips. The whole structure is tension with steel cables. Its observation platform is 18 metres high and offers views far across the Eifel and to the Hunsrück. For example, Klausen and its pilgrimage church may be seen.
