NEWTOWN ANNER HOUSE (above), near Clonmel, County Tipperary, is a two-storey late-Georgian house with a nine-bay front, the three outer bays breaking forwards and elevated an extra storey above the centre block.
Newtown Anner was formerly a seat of the Osborne Baronets; as was Beechwood Park in County Tipperary.
The doorway has engaged columns and a large semi-circular fanlight over the door and side-lights; with a curved two-storey bow at the side.
The Osbornes purchased the Newtown Anner estate from Clonmel Corporation in 1774, though the present house dates from 1829.
Newtown Anner passed eventually to the 12th Duke of St Albans, grandson of Ralph and Catherine Bernal (nee Osborne).
It was occupied by the Duchess of St Albans in 1906 and was still in that family's possession in the early 1940s.
It is now thought to be the home of Nigel Cathcart.
