The façade of Oak Park, County Carlow, designed by William Vitruvius Morrison in the early 1830s for Colonel Henry Bruen. The building incorporates an earlier house and was originally a grand villa, of two storeys and five bays, one on either side of the giant tetrastyle portico. The latter, featuring four Ionic columns with wreaths in the frieze above, is almost identical to that at Ballyfin, County Laois and can also be seen at Barons Court, County Tyrone and Mount Stewart, County Down, on all of which buildings the Morrisons, father and son, worked. Oak Park was greatly extended in the 1870s and also extensively restored after a fire in 1902, but some of the original interior decoration survives, notably in the entrance hall and the former library. The last of the Bruen family to live in the house died in 1954; some time earlier his wife had run away with an impoverished Montenegran prince, Milo Petrovic-Njegos. After various legal disputes and changes of ownership had occurred, Oak Park and several hundred acres was acquired by the Irish State; today it serves as the headquarters of Teagasc, the Agriculture and Food Development Authority.
