The old castle of the Landgrafen of Hesse today houses the district administration. The castle is also famous for the Dietemann, the figure of a man with a horn, the symbol of the Eschweger, which is located in the castle tower and appears every hour to blow its horn. Also scenic are the views along the river Werra.
Eschwege is the home of a famous four day music and drinking festival called the Johannisfest, which attracts several thousand visitors and is said to be the best showcase of the quaint town besides the Open Flair, the largest music festival in the region.
Eschwege is also home to an old barracks, formerly used by the Germany Army during World War II. It was occupied by US Army troops for a short time after the war and is now a training centre for the German Federal Police.
