Tudoburg, Medieval castle ruin near Eigeltingen, Germany

Tudoburg is a ruined spur castle at 615.8 m above sea level near Honstetten in the Hegau. Its large outer bailey, roughly 136 by 36 metres, lies on a plateau bordered by two incised streams; a deep double neck ditch separates it from the smaller main castle, whose palas north wall survives to shield-wall height.

The fortress was built between 1050 and 1150 by the Lords of Honstetten under its original name Harperg. It later became known as Tudoburg after Tuto von Wagenhausen, who had ties to the site.

The name comes from Tuto von Wagenhausen, an early owner whose memory is preserved in what the fortress is called today. Visitors can see the open meadow in the outer bailey where local people gather for barbecues and community events.

From the road between Eckartsbrunn and Honstetten, a path branches off south just before the cemetery and leads gently downhill to a visitor car park at the edge of the Krebsbach valley. From there, a short walk brings you to the overgrown rampart of the outer bailey. The site is freely accessible; sturdy footwear is useful on the uneven, wooded ground.

A V-shaped double moat separates the inner fortress from the outer bailey, creating an unusual defensive feature that catches visitors by surprise. This structure shows how carefully early builders planned the defenses of this hilltop location.
