Summerhill House was a 100-roomed Palladian house in County Meath, Ireland which was the ancestral seat of the Viscounts Langford and the Barons Langford. Built in 1731, it was likely designed by Sir Edward Lovett Pearce and completed by Richard Cassels in the Palladian style, although Sir John Vanbrugh, who was related to Pearce and with whom he trained, is thought to have also influenced the design of the house, which could be seen by the Baroque details, great arched chimney stacks and the palatial grandeur and scale.
The house demonstrated the power and wealth the Langford Rowley family had at the time. They owned vast amounts of land in counties Meath, Westmeath, Cork, Londonderry, Antrim, and Dublin as well as in Devon and Cornwall in England. The house also welcomed royalty, and ranked architecturally amongst the finest and most modern mansions in Europe.
