1553 Map of Leix and Offaly has the words 'Bawn Regan' written across the present townland of Tinnahinch near the Barrow. Tinnahinch Castle is mentioned in the 1637 inquistion taken at Maryboro (Portlaoise) when Charles Dunne is described as being posessed of the 'Castle of Tinnahinchie, the hall, the chambers at the end of the hall, the stone wall of a hall which joineth to the castle, the kitchen, the brewhouse, the back-house, the stables, the porter's lodgings and all the houses within the bawn; the two gardens, the four orchards, the park and the meadow on the south syde of the castle, the myll and all the houses on the easte side of ye river of the Barrow in the towne and fields of Tinnahinchie in the territory of Iregan (Crosdaile 1959, 12). Unlocated castle within the townland of Tinnahinch. This castle continued to be the chief seat of the O'Dunne's until it was attacked by Colonel Hewson in 1653.

Tinnahinch Castle was likely built by the Regan family, as indicated by the reference to "Bawn Regan" on the 1553 map, and was held by them or their successors in the early 17th century. It is remembered for its mention in the 1637 inquisition, highlighting its presence in local legal and land records during a period of English administration in Ireland.
