The Maldovarium

The Maldovarium, or the Maldovar Market, was a market settlement in the 52nd century, with a bar and a black market. River Song went there to get a vortex manipulator from the bar's owner, a blue-skinned alien named Dorium Maldovar. A humanoid with red skin was also in the bar while River Song was there. (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)
