The 2nd Earl and his wife Caroline, having spent the early years of their marriage visiting many beautiful country houses in England and Ireland, had long discussed making significant changes to Adare House. When the active and energetic Earl found himself largely confined indoors by a crippling case of gout, Lady Caroline inspired him to at last take up the project of rebuilding the house in grand gothic style. The couple commissioned two architects, the brothers James and George Pain, to help them begin the transformation. The Pain brothers’ most important contribution to the Manor was the Gallery. The idea had come from Caroline and Windham who had a love for cathedrals with long naves, soaring arches and picturesque glass. At 132ft 6in long, 21ft wide and 21ft 6in high, the Gallery was the largest domestic room of its age in Ireland.
