 COMO Metropolitan London now occupies the site of Londonderry House.Holdernesse House, later Londonderry House, was designed by Athenian Stuart for Robert Darcy, 4th Earl of Holderness in the period c. 1760–5, with ceilings based on Robert Wood's "Ruins of Palmyra".The Earl is thought to have acquired the building next door as well, but at a later date.
