Find the Sogdian Rock
The Sogdians must have felt sorely cheated by fate. In 327 BC Alexander the Great rampaged through Central Asia in an attempt to create a global empire, and the Sogdians were, put simply, in the way. The King of the Sogdians, Oxyartes, sensibly placed his wife and daughters in the fortress known as the Sogdian Rock near Penjikent - known as such because of its supposedly impregnable position - but Alexander conquered it anyway, creating his own myth whilst doing so. He eventually married one of the daughters, Roxana. Nobody is quite sure of the location of the rock, though Colin Thubron in his book The Lost Heart of Asia found some plausible candidates. If you do manage to find it, do let UNESCO know.
