What is "schauinsland"

The Schauinsland (literally "look into the country"; near Freiburg im Breisgau, Germany), is a mountain in the Black Forest with an elevation of 1,284 m (4,213 ft) above sea level. It is a popular destination for day trips. Due to the high amount of silver mining, it was previously known as “Erzkasten” (literally “ore box”); the name “Schouwesland” first appeared in 1347. The mountain is located roughly ten kilometres south-east of Freiburg’s city centre.
