WALTERSTONE is a parish and village situated on the river Monnow, which here divides the counties of Hereford and Monmouth. It is distant 7 miles N.N.E. of Abergavenny, 16 S.W. of Hereford, 3½ S.W. of Pontrilas, and about 1 mile N. of Pandy railway stations on the West Midland section of the Great Western railway. It is in Ewyas Lacy hundred, Dore union and petty sessional division, Longtown polling district, and Abergavenny county court district. The population in 1861 was 173; in 1871, 144; inhabited houses, 37; families or separate occupiers, 38; area of parish, 1,241 acres; annual rateable value, £1,107. The Marquess of Abergavenny is lord of the manor of Ewyas Lacy. The principal landowners in Walterstone are Messrs. David Morgan Jones, John Rogers, Aaron Rogers, and Jeremiah L. Roshier, Esq. The soil is red clay on a red sandstone formation; chief produce, wheat, barley, oats, &c.

Walterstone is in the diocese and archdeaconry of Hereford and rural deanery of Weobley. The living has been constituted a vicarage under the District Church Tithes Act, 1865 (28 Vict. c.42), and was gazetted as such November 20th, 1866. The annual value is £50, with 66 acres of glebe; patron, William Barneby, Esq., of Saltmarshe castle, Bromyard; vicar, Rev. Theophilus Morgan, who was instituted in 1830, and resides at Glan-Honddû house, Llanfihangel-Crucorney, Monmouthshire. The church, dedicated to St. Mary, is an ancient stone edifice, in the Early English style of architecture, consisting of nave, chancel, porch, and small tower containing two bells. It was restored in 1865, under the superintendence of Thomas Nicholson, Esq., F.I.B.A., of Hereford, the diocesan architect. The parish registers commence with the year 1761.

A school board has been recently formed for the united district of Walterstone, Rowlstone, and Llancillo, and a school is about to be erected from the designs of Messrs. Haddon Brothers, architects, of Hereford and Malvern. The Primitive Methodists have a chapel here. There are two camps in the parish, one Norman, the other supposed to be Roman; there is also a circular moat near the church, in the centre of which it is possible there was once a castle, but there are no traces remaining to show that such was the case. Altyrnnis, the principal farm-house in the parish, now the residence of Mr. John Rogers, was formerly the property and seat of the Cecils, from whom descended the Lords Burleigh.

This estate became the property of the Cecils by the marriage of Robert Sitsilt with an heiress about the year 1091. This ancient mansion is situated near the junction of the rivers Monnow and Honddû the latter nearly surrounds it; both streams are clear and rapid, and the scenery on their banks is very picturesque. It still retains some of the remains of its ancient grandeur, and had, until the last few years, the arms of Burleigh in painted glass in the window. One of the Lords Burleigh was the able minister to Queen Elizabeth. Near the Black mountains, in the hamlet of Bwlch-Trewyn, and parish of Cwmyoy, Monmouthshire, and on the verge of Herefordshire, is Trewyn House, the pleasant seat of Jeremiah L. Roshier, Esq.
