Tannenburg

Tannenburg presents a late Staufer-period hilltop plan arranged along a narrowing rocky spur, with three successive defensive ditches cut across the approach, a large inner courtyard and a principal residential block containing a great hall. The castle occupies the western ridge of the Tannenberg at roughly 485.7 metres above sea level and stands about 110 metres above the Bühler valley; the Bühler river runs about one kilometre to the west. The spur narrows toward the west and falls below one hundred metres in width at a point roughly three hundred metres before the main shield wall.

A massive, walkable shield wall defends the most exposed side of the site. Built to a thickness of about four metres, this barrier protected the approach and was paired with a gate building that controlled access on the attack side. The three neck ditches form a sequence of obstacles across the neck of the spur and remain visible as integral parts of the defensive layout.

The principal residential block, often called the palas, sits within the courtyard and includes the site’s great hall on a trapezoidal ground plan. Exterior wall faces display bossed ashlar masonry, where squared blocks carry raised rounded centres, indicating high-status medieval stonework. On the southern side the palas rises above its stone lower walls with projecting timber-frame storeys, a later technique that was built above the earlier masonry.

The small castle chapel dedicated to St. Mary Magdalene stands near the southwest corner of the outer yard that served as a cattle enclosure. The chapel measures about fifteen by ten metres and rests on 13th-century foundations. The building combines Gothic and Renaissance elements, and its mid-17th-century bell is marked with the date 1649. The chapel survived later administrative changes and continued in ecclesiastical use for long periods, remaining available for occasional services today.

Survival and later use are part of the site’s character. The curtain of defensive masonry, the palas with its surviving fabric, and the three neck ditches remain visible and substantial, making the castle one of the better-preserved examples of a shield-wall stronghold in the Württemberg region. The castle courtyard contains a summer lime tree that has been formally protected as a natural monument, and the surrounding lands continue to be used in connection with the property’s current functions as a school and organic farm.
