Alarmstange, Mountain summit in the Montabaur Heights, Rhineland-Palatinate, Germany

Alarmstange is the highest point of the Montabaur Heights, a ridge on the southwestern edge of the Westerwald, reaching 545.2 m above sea level near Horressen in Rhineland-Palatinate. About 130 m southwest of the summit stands the 99-metre Hillscheid-Alarmstange telecommunication tower, built in 1971, and another tower stands about 20 m west of the summit.

In 1809 French soldiers built an optical signal station on the summit, which gave the mountain its name. A post erected in 1853 served as a trigonometric point for the Rhineland survey begun by Jean-Joseph Tranchot and continued by Friedrich Carl Ferdinand von Müffling, and from 1894 for the Prussian state survey. In 1969 the post was moved about five metres and a granite post was set up in its original place.

The name Alarmstange comes from the optical signal station French soldiers set up on the summit in 1809. In 1853 a post was erected as a trigonometric point for the Rhineland survey begun by Jean-Joseph Tranchot and continued by Friedrich Carl Ferdinand von Müffling; from 1894 it served the Prussian state survey. The post was moved about five metres in 1969, and a granite post was placed at its original spot.

The peak is accessible from several hiking trails suited to different skill levels, and the routes are generally well marked for easy navigation. Expect to encounter both day hikers and mountain bikers on the main paths.

The 99-metre Hillscheid-Alarmstange telecommunications tower, built in 1971, stands about 130 metres southwest of the summit and carries an amateur radio relay; 150 metres west of it is the Neuhäusel air-quality measuring station of the ZIMEN network. About 20 metres west of the summit itself is a second, smaller telecommunications tower.
