Darmstadt's greatest period was during the reign of Ludwig X (1790-1830), a hundred-foot statue of whom still stands in modern Darmstadt. During his regin the city was largely rebuilt. Through much of the nineteenth century, Darmstadt was known for its importance as a center of the chemical industry, especially after the founding of the technical university in 1836.
A Frankenstein Castle stood in Nieder-Beerbach, a village near Darmstadt, but there is no evidence that the Shelleys knew of it: see title page and note.
