Located in the historic town of Listowel, this castle stands on an elevation on a steep bank, overlooking the River Feale, above the location of a strategic ford.

The construction date of the earliest castle at Listowel dates to the 13th century but the present castle was probably built in the 15th century by the FitzMaurices.

A substantial part of the front of the castle survives consisting of two large, square towers of four storeys, standing almost to the original height of 15.3 metres, connected by a wall of the same height and linked together by an arch on one side.

A major programme of conservation works has been undertaken at the castle including the provision of an external staircase to allow public access to the upper levels
