Huis te Vliet, Oudewater, Medieval castle ruins in Oudewater, Netherlands.
Huis te Vliet is a castle ruin in Oudewater consisting of the remains of a medieval fortification that once stood along the Hollandsche IJssel river. The most visible part today is a brick wall fragment that survives near Goudse Straatweg, standing within open countryside away from the town center.
The fortress was built in the later 1200s to protect the border between Holland and Utrecht while monitoring river traffic. It was part of a defensive network established by the van Woerden family across the Sticht region.
The castle belonged to Gerrit van Woerden, whose family constructed multiple fortifications throughout the Sticht region during the medieval period.
The ruin is located along Goudse Straatweg near house number 67 in open countryside and is visible from the road. It is easily accessible on foot and gives a sense of the medieval structure within its rural setting without barriers or restrictions.
The site still has portions of its original moat surviving on two sides, which historical maps from the 1700s show as a complete water-filled barrier surrounding the entire structure. These remaining moat sections give visitors a hint of the water defenses that once protected this border fortress.
