Included in the town were a new railway station, with a reception area for Hitler and his guests, and an adjacent post office.

The "Kehlsteinhaus" (known as the "Eagle's Nest" among the Allies) atop the Kehlstein subpeak of the Hoher Goll was built as a present for Hitler's
Retreat of glaciers since 1850 in those areas. The retreat of mountain glaciers, notably in western North America, Asia, the Alps and tropical and subtropical regions of South America, Africa and Indonesia, provide evidence for the rise in global temperatures since the late 19th century. The acceleration of the rate of retreat since 1995 of key outlet glaciers of the Greenland and West Antarctic ice sheets may foreshadow a rise in sea level, which would affect coastal regions. The mass balance, or difference between accumulation and ablation (melting and sublimation), of a glacier is crucial to its survival. Climate change may cause variations in both
