I claim no prior knowledge about this, but I googled "Karl-Hermann Frank 1944" and turned up the same photo at this websitehttp://www.geocaching.com/seek/cache_de ... bc2532658a
According to google translate, the site was originally intended to be a boarding school for German youth in the Protectorate, but on the initiative of Arthur Seyss-Inquart (who was born in Jihlava / Iglau) it was designated in 1943 as an Adolf-Hitler-Schule, one of a chain of elite boys' schools projected to be built across Germany. The schools were a joint project of Education Minister Bernhard Rust, HJ Leader Baldur von Schirach and DAF Leader Robert Ley. This articlehttp://de.wikipedia.org/wiki/Adolf-Hitler-Schulen
confirms that Iglau was designated as the site for the 12th Adolf-Hitler-Schule.
Nice photos, by the way. What is it now?
