Burg Frankenstein in Mühltal

You're standing at Frankenstein Castle, high on a hilltop at the edge of the Odenwald, about 370 metres up. Look down for a moment: that's Darmstadt below you. And yes, that name. Frankenstein sounds like a horror story, but it simply means 'stone of the Franks'. It refers to the rock the castle sits on, and around here it's a pretty ordinary name for a castle.
