It lies on the N70 national secondary road between Killorglin and Tralee. The village takes its name from the castle of Castle Maine that once stood on a bridge over the River Maine at the current location of Castlemaine. Until the seventeenth century the river formed the boundary between the Norman territories of the Fitzgerald family and the Gaelic lordships. The castle was originally built on a rock in the centre of the river in 1215 by the Fitzgeralds, marking the southern limit of their newly conquered territory. It remained in the possession of the Earls of Desmond until the 1570s, when it became an English Crown fortress, overseen by a constable. The constable held considerable power in the locality and could raise taxes from the town that emerged near the castle. The first constable was Thomas Spring. The castle's strategic position made it a valuable building, and it was besieged for 13 months in 1598–1599 during the Nine Years' War. During the Irish Confederate Wars of the 1640s the castle changed hands on a number of occasions, before being finally destroyed by a Cromwellian army in 1652. Despite the destruction of the fortress, a Constable of Castlemaine Castle continued to be appointed until 1832, receiving income from the fisheries and fairs of the town and river.
