p. 222. (Brereton/IFR; Dixon, Glentoran, B/PB; Urquhart/LGI1958) A house built of two storeys over basement, built ca 1755 near the site of a Franciscan abbey founded 1486 and afterwards leased to Edmund Spenser, who probably wrote most of the six books of the Faerie Queen here. Entrance front with one by on either side of a central three sided doorway; three bay side elevation. Urns on roof parapet. Acquired 1779 by George Brereton, who was killed in a dual in Dublin two years later. The astragals of the windows removed during C19, and post 1864, a partly-glazed Doric porch surmounted by a little glazed kiosk added on the entrance front by Major Robert Brereton, who also added a low wing to the right of the entrance front 1901. Sold 1909, almost immediately resold to Capt Herbert Dixon, afterwards 1^st Lord Glentoran, who added a two storey two bay wing to the left of the entrance front and set back from it, obscuring one bay of the original block and in a similar Georgian style, with urns on parapet and astragals in the windows. Surprisingly, at the same time he did not put back the astragals in the original block. Subsequenty sold again, and now the home of Mrs Kenneth Urquhart.”
