HISTORY

Emblem as company logo

In 1728, the Kupferhütte (copper smelter) was donated by Prince Christian to his wife Isabella Charlotte Princess of Nassau-Dillenburg. The name was changed into Isabelle Kupferhütte.

The gate decoration dated 1734 includes the crowned initials of Isabella Charlotte Fürstin zu Nassau (I. C. F. z. N.).

Today, it is the logo of Isabellenhütte.
