Long Walls
After being convinced by Conon that allowing him to rebuild the Long Walls around Piraeus, the main port of Athens, would be a major blow to the Lacedaemonians, Pharnabazus eagerly gave Conon a fleet of 80 triremes and additional funds to accomplish this task. Pharnabazus dispatched Conon with substantial funds and a large part of the fleet to Attica, where he joined in the rebuilding of the long walls from Athens to Piraeus, a project that had been initiated by Thrasybulus in 394 BC.
