Alexandria Carmania

Alexandria Carmania (, "Alexandreia hē en Karmania") was one of the seventy-plus cities founded or renamed by Alexander the Great.
The town was founded by Alexander in January 324 BC after his army had reunited with Nearchus and his men who had beached their boats near the mouth of the Minab River. 
Location.
The exact site of the city in Carmania is still unknown but several locations have been proposed:
The main contenders are all within a few kilometres of each other and that area would seem a logical one. Provided with reliable water from the Minab river, the location was on the convergence of the main passes from Afghanistan, the route into Gedrosia and had good access to the nearby Indian Ocean ports at Hormosia. The location would also provide control of the arable parts of Carmania.
The city still existed in the medieval period being known as Camadi, when Marco Polo visited. If Galashkird is the now lost city it was described by Arab geographer Mukaddasi who described it as "a strongly fortified town with a castle Kushah," and lush orchards and fields supported by extensive qanat irrigation.
