Dyleň

Dyleň (Tillenberg) is a mountain in the Karlovy Vary Region of the Czech Republic. At 940 m above sea level, its summit is the second-highest peak in the Upper Palatinate Forest.

The summit is located in the Stará Voda municipality. It lies about 600 m east of the Czech Republic–Germany border.

Local tradition holds that Napoleon Bonaparte declared Tillenberg the geographical midpoint of Europe in 1813.

The German name provided the title of the epic poem Der Tillenberg: Ein Sagenschatz aus dem Egerlande (A Treasury of Tales from the Egerland) published in 1904 by Ernst Freimut (pseudonym of Johann (Hans) Sommert).

On the summit is a set of prominent buildings, which were used by the Soviet Union for electronic espionage into Germany during the Cold War. Now it is a radio and television transmission tower.
