Schloss Heiligenberg (Jugenheim)

Schloss Heiligenberg is a castle to the east of Jugenheim, part of Seeheim-Jugenheim, about 12 kilometres to the south of Darmstadt, Germany.

It is built on the Heiligenberg, with panoramic views of the Rhineland as far as the Palatinate.

It is now the headquarters of the Amt für Lehrerbildung, though its 'Gartensaal' is occasionally used for concerts and art exhibitions.

Alexander (1823–1888), third son of Grand Duke Louis II of Hesse-Darmstadt, from 1852 onwards mainly lived in Darmstadt or at the Schloss Heiligenberg, at least when he was not on campaign.

On 28 October 1851 he entered a morganatic marriage with countess Julia Hauke, a lady in waiting to his sister, Tsarina Maria Alexandrovna of Russia.
