Hogatha´s castle is a location that appeared in the Smurfs cartoon show.
In the Season 1 episode where she first appeared, "Bewitched, Bothered, And Be-Smurfed", and its follow-up "The Fake Smurf", Hogatha lived in a dark castle that stood on a hill outside the Smurf Forest with her vulture Harold. She lost her grandmother Dogatha's magic locket in the forest, where it was found by Smurfette and inadvertently used for her own wishes. It was later destroyed by the Smurfs, costing Hogatha one of her nine lives. After regenerating, Hogatha swore revenge on the Smurfs by disguising herself as a fake Smurf, but her plan backfired when her masquerade was exposed.
From Season 3 onward, Hogatha lived in a different castle with four towers that had a moat, a bridge, and a dragon named Louise that appeared only in one episode.
