Jerusalem was a place on Earth.
The First Doctor and Susan Foreman once visited Jerusalem prior to their meeting Ian Chesterton and Barbara Wright. They visited the city around the time of the 1st century, and the Doctor found it a "brutal and murderous place." He went on to call it "terrible," replete with "slavery, crime in the streets, everybody stabbing everyone else in the back." (PROSE: Byzantium!)
During the Third Crusade in 1190, the European Christian forces hoped to retake Jerusalem from Muslim occupation. However, they were unsuccessful. The First Doctor told Vicki Pallister that Richard the Lionheart would only see the city from afar. (TV: The Crusade)
