Thomastown Park House, built during the mid eighteenth century for the Leggat family and in the ownership of the Bennett family during the nineteenth century, was once a large and important estate within County Offaly. The house even had a private chapel. Though the country house itself is no longer extant, the associated structures of the demesne remain. Notable elements include the large walls which surround what once was a deer park, the finely tooled limestone entrance gates, the walled garden and the outbuilding with ashlar bellcote.
