Ham House is a 17th-century pile between the river and Petersham. It's had a long list of famous residents from the courts of many British kings and queens through the years. Its attractive red bricks are quite distinctive, so even if you just stop outside it's worth it.

Severndroog Castle is an elegantly preserved Gothic tower situated on Shooter’s Hill, one of the highest points in London. Not an actual castle but an 18th Century folly. It has a cafe and viewing platform. The surrounding woodland is known as Castle Wood which is part of Oxleas Woods. Lots of tracks and trails, many fast and hilly, are located around the tower.
