From the mid-eighteenth century Irish country houses flourished. Landowners generated easy income leasing land to tenants. As their wealth increased so did the size of their country mansions. But factors such as the Great Famine land reforms the increasing expense of maintenance & the IRA targeting the houses during the War of Independence took their toll. Gradually abandoned & forgotten the houses sank into decay. In 2008 Tarquin Blake found his first abandoned ' Big House' & so began exploring the lost architecture of Irel&. Here he documents what is left of fifty mansion houses with brief histories & beautiful photographs of the haunting ruins. Included are Mountpelier Lodge (Dublin Hellfire Club) the birthplaces of Daniel O' Connell & the Duke of Wellington & the one-time homes of Grace O' Malley & of brewing family the Smithwicks of Kilkenny. The inclusion of details from the 1911 Census offers a glimpse of the closing days of the aristocracy & their mansions.
