A Hutt Citadel was a fortress owned by a Hutt. Jabba Desilijic Tiure had such a building on Tatooine in 33 BBY. Unlike the tri-domed structure of his palace, the Hutt Citadel of Jabba's was a series of mostly flat-roofed cylindrical towers, with Ion attractors in the center of each one, that housed craft including many Hutt atmospheric flyers to rout attacking forces and a shuttle.
