Alexandria on the Indus (, likely modern Uch, Pakistan) was a city founded by Alexander the Great at the junction of the Indus and the Acesines river. Arrian tells that colonists, mainly Thracian veterans and natives, were settled there. The satrap of the west bank of the Indus, Philip, son of Machatas, was put in charge of building the city: Today, the remains of the Greek town are thought to be inside the citadel mound, although a shift in the river has caused significant damage to the mound. A UNESCO listing applies to the site.
