Hof Armada, Fortified farm in Frauenstein, Germany.

Hof Armada is a former fortified farmstead in Frauenstein, now a horse boarding stable and educational farm, protected as a cultural monument under Hessian law. Its buildings are grouped around an inner courtyard: the main house of 1856 with a hipped roof, seven window bays and a central risalit, farm buildings from 1839, and modern additions. The southwestern building served as a horse stable until its conversion in 2011.

Hof Armada was first mentioned in 1317 as "zur Armen Ruen"; a chapel "zom Armode" was built in 1341 by the knight Sifrid von Lindau. The chapel was destroyed in the Thirty Years' War, and a fire ruined the buildings in 1832. The Dukes of Nassau rebuilt the farm from 1839, and the present main house dates from 1856.

The name Armada probably comes from "zur Armen Ruen", meaning rest, first recorded in 1317. Knight Sifrid von Lindau built a chapel "zom Armode" here in 1341 in honour of Saint Catherine; it was destroyed in the Thirty Years' War. Pilgrimage processions from the Mainz area still came here in 1594.

The farm lies at 161 m on the Erlenbach above the Grorother Hof, below the Sommerberg nature reserve; the Walluf municipal boundary runs just west of it. The buildings enclose a courtyard, with the 1856 main house in the southeast and its entrance stair leading to the animal pastures and a small lake. Access is via the lanes from Frauenstein or the Erlenbach valley.

The farm's name appears in records as "zur Armen Ruen" in 1317 and as "Turm zum Armudt" in the 1427 fief books, when it served as a knight's seat of the von Lindau family under Nassau. Knight Sifrid von Lindau built a chapel here in 1341 dedicated to Saint Catherine; it was destroyed in the Thirty Years' War.
