George Dowdall built a strong gatehouse, Althumney House near Navan, County Meath; it was a building of the 15th century that was later enlarged and fortified by other Dowdalls. In 1630 a long, narrow gabled mansion with large mullioned windows and an oriel window was added.^[4] Today, it lies in ruins near the River Boyne.

The tower house had four storeys, with an attic and four projecting corner turrets of different sizes. Inside the manor house, there are small hidden latrines and chambers, where the Catholic Dowdalls used to hide priests.

The mansion was supposedly burnt in 1649 as "one of ye families of ye Maguires was living in it when Oliver Cromwell took Drogheda and to prevent Oliver from getting any shelter or subsistence there, set ye stately fabric on fire which consumed all ye curious apartments which were said to be very rich and costly".

The Dowdall family coat of arms depicts three red birds on a red and white background. White was meant to represent pureness and at harmony, whilst red was meant to be suffering that Catholics endured.
