Daingean, in the east of County Offaly between Tullamore and Edenderry, is well known as the place where the Grand Canal was opened in 1797.

A well preserved 2000 year-old body was found in a nearby bog at Croghan Hill in 2003. The body dates from the iron-age. It's known as Old Croghan Man. There's an 18 hole golf course nearby at Castle Barna Golf Club.
