Not in nearly the decent shape that Sarvar is in, Csejthe (chey-tey) castle is a ruin, infamous as the site of the tower where Erzsebet was walled up for the last 3 1/2 years of her life. The entrance and wall are still standing, but much of the castle itself was destroyed by the Rakoczis in the early 18th Century. Locals say the place is haunted, either by Erzsebet or her victims, and apparently people like to visit on Halloween and listen for the wails of the bloody lady. It was even the subject of an episode of Ghost Hunters International, though I find it infuriatingly sloppy when television shows and other "official" outlets like this repeat fiction as if it's fact (see Erzsebet's fictional 650 victims and blood-bathing, etc). Could they not do even the tiniest bit of research? Wikipedia has better sources than they do.
Whenever I see these photos I always think of Jennifer Egan's novel The Keep and wonder if this was the castle that inspired her story.
