Hospital (World Enough and Time)

A Hospital was present on the 1056th floor of a Mondasian Colony Ship on which the Twelfth Doctor, with Bill, Nardole and landed on.

After being shot through the chest by Jorj, Bill arrived at the hospital on floor 1056 to be "repaired". There, she encountered a surgeon, a nurse and a disguised. Over the years, the technology grew more advanced and Bill soon became the first fully cybernetic humanoid. (TV: World Enough and Time)

After the Twelfth Doctor altered the Master's controls to have the Cybermen convert two hearted beings as well as humans, they fought off the army of Mondasian Cybermen on the hospital floor until Nardole collected them in a shuttle pod so they could evacuate to Floor 0507. (TV: The Doctor Falls)
