The Maldovarium, or the Maldovar Market, was a market settlement in the 52nd century, with a bar and a black market (TV: The Pandorica Opens) located in an unnamed planetoid. (AUDIO: The Light Keepers)
Having stolen Dalekanium-eating Vashta Nerada from Synthesis Station, Dendry planned to sip cocktails with his buyer at the Maldovarium only to be devoured by the Vashta Nerada before he could make his appointment. (AUDIO: Day of the Vashta Nerada)
River Song went there to get a vortex manipulator from the bar's owner, a blue-skinned alien named Dorium Maldovar. (TV: The Pandorica Opens)
Dorium later met with Madame Kovarian and Colonel Manton there while closing the bar down. He was decapitated by the Headless Monks on the same day. (TV: A Good Man Goes to War) However, this did not lead to the end of the Maldovarium, as Dorium survived as but a simple head. (TV: The Wedding of River Song)
The Maldovarium market was also the place where the Eleventh Doctor found Handles, the head of a decapitated Cyberman, who became his aide and companion. (TV: The Time of the Doctor)
Colony Sarff went to the Maldovarium as they searched for the Twelfth Doctor, but was unable to find him. (TV: The Magician's Apprentice)
