Siege of Kyropolis (288 - 287 BC)

The Siege of Kyropolis was a siege during the Seleukid-Atropatene War.

Kyropolis is a port city on the Caspian sea and important trading settlement in the region. Capturing it was one of the main goals of Seleukos I Nikator during the war. The city, however, proved to be well defended and easy to resupply resulting in a long drawn out siege lasting well over a year.
