Eschenburg, Mountain summit in Hesse, Germany

Eschenburg is a 589-metre hill of the Gladenbach Uplands, the highest point in the borough of Dillenburg. Its summit lies about 6.5 km northeast of Dillenburg's centre, 1.5 km north-northeast of Nanzenbach and 1.4 km east-southeast of Wissenbach. The Dietzhölze flows past to the northwest and the Nanzenbach to the southeast; on the southeastern flank stands the Hörlestein natural monument.

A 43-meter wooden tower with a stone base was built at the summit and housed a mining museum. American forces destroyed it in 1945, but its stone foundation influenced the area's reconstruction after the war.

The hill gave its name to the municipality of Eschenburg, not the reverse; the community lies to the east of the summit, around Wissenbach. The 43-metre wooden Eschenburgturm, inaugurated on 20 June 1936, drew visitors from the Gladenbach Uplands, Westerwald and Rothaar Mountains before its destruction on 23 March 1945. A several-metre-high model of the tower now stands on the hill as a reminder.

Several marked hiking trails and mountain biking routes of varying difficulty levels cross the mountain and connect to nearby destinations. The paths are well-signposted and allow visitors to choose their route based on fitness and time available.

The 1936 wooden tower was 43 metres tall and held a mining museum in its stone base. After American fighter-bombers burned it on 23 March 1945, the base stones were reused in post-war rebuilding. Today a several-metre-high model of the tower stands on the hill as the only reminder of the original.
