Little France, Medieval defense tower in Erlenbach bei Dahn, Germany.

Little France is a medieval defense tower near Erlenbach bei Dahn, standing at 322 meters above sea level on the northern slopes of Nestelberg mountain. The structure features walls approximately 3 meters thick with several weapon embrasures visible in the remaining battery tower.

Knight Hans von Trotha built Little France in 1484 as an outwork of Berwartstein Castle. Its purpose was to bring the open ground called Leichenfeld under crossfire from north and south, since that saddle was the only spot where siege cannons of the time could be placed near Berwartstein. Berwartstein was never retaken before 1591, when it burned after a lightning strike. The outwork was badly damaged in the 17th century, in the Thirty Years' War or the War of the Palatine Succession, and restoration of the remains began in 2005.

The name's origin is still unexplained. From Berwartstein the site faces France, whose present border lies only 7 km away; in 1511 a document recorded it as Thurm Frankreich ("France Tower"). Locals know the saddle below as the Leichenfeld ("corpse field"), the open ground the outwork was built to cover with crossfire.

The last stretch is on forest paths closed to public motor traffic, so the ruin cannot be reached by car like Berwartstein. Drive from Dahn on the B 427, L 490 and K 50, continue about 150 m past the turnoff for Berwartstein along the eastern edge of the Leichenfeld, and park at the roadside. From there a walk of roughly 500 m climbs about 70 m to the outwork.

The supposed tunnel to Berwartstein is speculation, not confirmed fact: it arose because near the outwork lie the remains of a ditch covered with stone slabs and hidden under earth and vegetation, now almost entirely collapsed. The name's origin is likewise unexplained, though from Berwartstein the site faces France, 7 km away.
