Thrace

Thrace was a region in Europe, at the Bosphorus strait and Black Sea. The city of Byzantium (later known as Istanbul) was located in Thrace, which was part of the Roman Empire in the 1st century, albeit in the form of various free city-states with protectorate status, at least until 73 AD. According to one account, the Doctor's TARDIS materialised in Thrace in 64 shortly after leaving Dido, (PROSE: Byzantium!) although another account supposed that it instead materialised near to Rome. (PROSE: Romans Cutaway)
