Burg Schlierbach, Medieval castle in Langstadt, Germany

Burg Schlierbach, also called Langstädter Burg, is a vanished small castle, probably only a fortified residential tower or Kemenate, located about one kilometre southeast of Langstadt on the boundary between Langstadt and Schlierbach. Its exact site is unknown; only the Burgweg path and written records attest to its existence. A small wood east of the Straßenmühle, formerly a medieval quarry, shows similarities to ramparts, ditches and tower remains.

The castle's origins are unknown; it is thought to relate to Schlierbach, first mentioned in 770 in a donation to Lorsch Abbey. From 1393 the von Wasen and von Düdelsheim held it as a fief of the lords of Hanau, with fief letters naming it nine times between 1452 and 1539. By then it was likely already a ruin, used in charters only to locate the land.

The name Langstädter Burg links the vanished castle to Langstadt, about one kilometre northwest. The connecting lane is still called Burgweg, and field names such as "an dem Weinberg" and "Wingertsberg" mark the area where the site is presumed to lie near today's Wingertsberg nature reserve.

The exact location of the vanished castle is unknown; only the connecting path called Burgweg and written records attest to it. The likely area lies near today's Wingertsberg protected landscape, about one kilometre southeast of Langstadt. A small wood east of the Straßenmühle, formerly a medieval quarry, shows features resembling ramparts, ditches and tower remains.

The castle's exact location is lost; only the field name Burgweg and old documents attest to it. In 1872, sandstone walls were uncovered during earthworks north of the Burgweg, and no further archaeological investigation has been carried out since.
