The Děčínský Sněžník (German: Hoher Schneeberg) is a mountain in the Czech Republic. It is, at 722.8 m (2,371 ft) above sea level, the highest peak of the Elbe Sandstone Mountains. The Sněžník is located in the Jílové municipality west of Děčín in the Ústí nad Labem Region, in the mountaineous area of Bohemian Switzerland, close to the border with Germany.
One of the first historical personality who took a pleasure in viewing from Děčínský Sněžník was Emperor Joseph II of Habsburg, who visited the peak in September 1779. The Sněžník was considered an important geodetic point of triangulation and the cartographers asked the owner of the Lordship of Děčín's, Prince Franz of Thun and Hohenstein, to set up the peak for measuring needs. Earl Thun entrusted the Dresden architect Karl Moritz Haenel to design a stone viewing tower. The construction of the Neo-gothic tower started in 1863 on the peak of Sněžník. The fracture finding in a close neighbouring answered for a source of building material. The construction was finished in autumn in 1864. The tower was orginally used by geodesists but the view attracted many visitors and in 1865 the local forest administration decided to built a small hostelry for them.
The view-tower at Děčínský Sněžník remained a popular tourist aim and lasted with small arrangements for more than 80 years. After the second world war the hostelry was abandoned that it had to be pulled down. Likewise the tower decayed in the 1980s was in a dilapidated stage. Vandals subscribed to the view-tower devastation, which started to drop its masonry. The view-tower was written down to The Monumentary Fond of State Monument Reservation, but this formal step did not bring any improvement. In 1992 two million korunas were collected for view-tower general rectification, made by the Děčín Kamason company, followed by the erection of a new inn. Since summer 1992 the tower at Děčínský Sněžník is again accessible to the public and the peak once again became a popular tourist aim. It offers a panoramic view over Bohemian and Saxon Switzerland right up to Dresden in the north and the Karkonosze ridge in the east.
The mountain summit is a stop on the European walking route E3. Ascents can be made from the small Sněžník village of Jílové or from the Saxon municipality of Rosenthal-Bielatal in the north.
