Troy

Troy was a city located in the far west of ancient Anatolia, part of Asia Minor, later Turkey. It was the site of the Trojan War, fought between the Greeks and Trojans circa 1200 BC. The Trojan king during the war was Priam. (TV: The Myth Makers)

The Rani had visited Troy during the war. (TV: The Mark of the Rani)

The First Doctor, Steven Taylor and Vicki visited Troy at the end of the war in circa 1200 BC and were partly responsible for the events leading up to the Greek victory. Steven immediately suggested that the Doctor give them the well-known idea of hiding inside a large wooden horse, however the Doctor resisted. Under pressure, and with other ideas having failed, the Doctor did ultimately suggest the idea to the Greeks. During this visit, the TARDIS crew met Katarina, who left in the TARDIS with the Doctor and an injured Steven. Vicki stayed behind with King Priam's young son Troilus, with whom she had fallen in love. (TV: The Myth Makers) The Ninth Doctor later recalled these events as he faced (seemingly) certain death in the hands of the Gelth. (TV: The Unquiet Dead)

The Fourth Doctor claimed not to have come up with the idea of the Trojan Horse, though his first incarnation had (somewhat unwillingly) given this idea to the Greeks. (TV: Underworld, The Myth Makers)

The Fourth Doctor later asked Drax if he had ever been to Troy, while the two miniaturised Time Lords were hiding in K9 much like the Greeks hid in the Trojan Horse. (TV: The Armageddon Factor)

In 1873, Heinrich Schliemann discovered the Jewels of Helen while excavating Troy. (PROSE: Past Reckoning)

In 2007, Mr Parson told the Tenth Doctor that one of his students could tell him the height of the walls of Troy in cubits. (TV: School Reunion)
