History

Although possibly of earlier origin, the present house was built in 1632 by Thomas Glynne, who had been High Sheriff of Caernarvonshire in 1626-7. Tenanted during the C18, the house was included within Glynllifon Park when this was enlarged in the 1820s. By the end of the C19 Plas Newydd had been reduced to ruins and c1900 it was extensively repaired by F G Wynne. A probate inventory made on the death of Thomas Glynne's widow, Jane, in 1688 gives much useful information on the house for this period and indicates occupation by a gentry family of some wealth.

Exterior

Original 3-storey and attic rectangular plan structure of 4 bays, aligned roughly north-west to south-east and possibly incorporating an earlier structure; 2-storey porch projection on north-east (entrance) front and similar but wider staircase projection on south-west side. Irregularly coursed rubblestone with buttered pointing (parts formerly rendered) with outlines of former roof pitches visible to gable ends; slate roofs with stone-coped verges. North-east elevation: tall gabled porch roughly to centre with room above entrance has 3-light wooden mullioned and transomed leaded windows (like virtually all windows in house renewed c1900) to front and returns and Gothic head to doorway (also c1900); stone water butt adjoining porch to right. Massive projecting lateral chimney immediately on left with tall shaft to top, the small space between on the ground floor infilled with a cloakroom; cross-windows to far left and right, repeated as 3-light windows on first and second floors, with on latter a further 3-light mullioned and transomed window above and to left of porch roof, those on second floor all of reduced proportions. Similar fenestration to north-west gable end; cross-window to right on ground floor, two 3-light mullioned and transomed windows on first floor with centrally placed cross-windows to second floor and attic, latter of reduced proportions; 3-light window to ground and first floors of south-east gable end and small cross-window to attic, both gables with integral end stacks. South-west elevation is most regularly composed with three 3-light mullioned and transomed windows on each floor, one tier to left and 2 to right of staircase projection and chimney, albeit that several of the windows are of different sizes (window to lower left in fact a cross-window); lead rainwater head dated 1632 to downpipe between 2 right tiers of windows. Gabled staircase projection has 3-light mullioned and transomed windows to front and right return, former above a tall narrow lean-to (c1900) with 2 cross-windows at front and to the left a pointed doorway approached by a contemporary straight flight of steps; prominent lateral stack immediately to left of staircase projection, similar to that on north-east elevation but flush with main wall.

Interior

Interior extensively remodelled c1900 as a result of the house's ruinous state by the end of the C19. All ceilings, floors, beams and roof structure are renewed, except for the collar-beam truss and chamfered purlins above the restored oak staircase; hall was until 1991 stone flagged. All internal partitions are also c1900 except for a fragment of plank and muntin partitioning adjacent to the staircase on the ground floor. Single large room on first floor has panelling of c1900 and there are 2 fireplaces, that to south-west with the carved emblem of the semi-mythical C10 warrior, Cilmin Troedd Ddu, and the date 1637. His arms appear again in a plaster shield on the second floor, this time with the initials TG and the date 1632, Thomas Glynne claiming ancestry from Cilmin Troedd Ddu; the room in which the shield is set and the landings on both the first and second floors have reused C17 panelling, some of it with foliated patterns in semi-circles.

Reasons for Listing

Included at II* as an important gentry house of the 1630s, which despite extensive work carried out c1900, itself of high quality and special interest, retains much original fabric and is illustrative of the social and architectural history of the period.
