Gleichen
groups of castles in Germany

Gleichen (German pronunciation: [ˈɡlaɪçn̩] ) is the name of two groups of castles in Germany, thus named from their resemblance to each other (German: gleich = like, or resembling).
Castles in Thuringia between Gotha and Erfurt
The first is a group of three (hence called "die drei [three] Gleichen"), each situated on a hill in Thuringia between Gotha and Erfurt.
One of these called Gleichen, the Wanderslebener Gleiche (1221 ft. above the sea), was besieged unsuccessfully by the emperor Henry IV in 1088. It was the seat of a line of counts, one of whom, Ernest III, a crusader, is the subject of a romantic legend. Having been captured, he was released from his imprisonment by a Turkish woman, who returned with him to Germany and became his wife, a papal dispensation allowing him to live with two wives at the same time (see Reineck, Die Sage von der Doppelehe eines Grafen von Gleichen, 1891). After belonging to the elector of Mainz the castle became the property of Prussia in 1803. The second castle is called Mühlburg (1309 ft. above the sea). This existed as early as 704 and was besieged by Henry IV in 1087.

Why this record matters
The phrase “groups of castles in Germany” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 19, 2025. The linked authority identifier is Q896257. Authority coordinates are 50.868, 10.851. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1221, 1088, 1891 and 1803.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
