Eisenberg Castle is a medieval hilltop castle ruin north of Pfronten, Bavaria, Germany built in the 14th century.
Eisenburg Castle was built in 1313, when the nobles of Hohenegg, deriving from the West of the Allgau, were deprived by force of their castle, Loch, by the Tyrolean. In consequence, they moved a few miles further north to establish their new lordship of Eisenberg which centered round a mighty new castle: Eisenberg. To visualize their power towards Tyrol/Austria, which held the closely sited castle of Falkenstein, Peter of Hohenegg decided to build Eisenberg in a most impressive manner: he placed it on top of a high mountain and surrounded the main castle with an exceedingly high curtain wall which gave the impression of a huge tower.
