|The medieval keep of castle Sterkenburg|
with 19th century additions
|Castle Weerdensteyn with the moat and entry gate|
But the real prize was the discovery of Castle Weerdensteyn, built around 1300 and hidden within a wood so it cannot be seen from any road. By chance we hit the path that passes it. The top of the keep is reasonably intact, but the base has been reworked in the late 19th century. Apparently it has been refurbished again recently and is still inhabited. Just shows that it pays not to stick to the beaten path.
There are dozens more in the area so I'll be keeping my eyes open. With the fortifications of the Oude Hollandsche Waterlinie also in the neighbourhood and the remnants of the Roman limes, which lay at the Kromme Rijn, this is an interesting place.
