The Letau prison facility is a detention facility located on Letau, a moon of Cardassia Prime. Prior to taking command of Terok Nor, Skrain Dukat was assigned as the warden of the Letau prison facility. While the posting was intended to be a punishment, Dukat used the opportunity to show his leadership skills. The assignment to Letau also shielded him from power struggles in the Cardassian Central Command and allowed him time to build alliances. (ST - Terok Nor novel: Night of the Wolves)
