Probably built mid to late C19, designed by W E Jones, architect of Llanfairpwll. Formerly known as Plas Mona, the present house is on the site of an earlier house, Plas Gwyn; owned by Reverend Henry Rowlands until his death in 1842 when it was inherited by the Evans family of Henblas, Llangristiolus. Sold in 1857 to Lady Willoughby de Broke, wife of the 16th Baron and daughter of Sir John Williams of Bodelwyddan, and for whom the house was probably re-built.

Single storey wings to rear of house now form entrances to individual dwellings within main block, linked by lean-to extensions.
