Pomorie, a seaside town about 20 kilometres north of Burgas, has now become a concrete labyrinth of high-rise hotels and apartment blocks thronged with Russian tourists and holiday-home owners. It does not sound particularly appealing – but that's only on the surface.
Amidst the dust, sun and crowds of Pomorie, there is a place of eternal silence and an unexplained mystery. To find it, you have to take a sign-posted lane off the congested Burgas-Nesebar road. This lane leads to a lush vineyard and there, hidden inside the cold embrace of a huge mound, is a tomb.
