ALLTMAWR (ALLT-VAWR), a parish, in the hundred of BUILTH, county of BRECKNOCK, SOUTH WALES, 4 miles (S. E. by S.) from Builth, containing 43 inhabitants. This parish, which is very small, and the name of which signifies the great woody mount, is bounded on the north by the river Wye, and is crossed by the turnpilce road from Builth to Hay: the scenery on the banks of the river, and in its immediate vicinity, is exceedingly picturesque and romantic, and the view from Alltmawr House, a pretty villa, the residence of George Holford, Esq., is one of the most delightful in this part of the principality. Its surface is, for the most part, undulating: in the low lands the soil is generally clayey, on which, or the shallow bed of loam by which it is overspread, the oak appears to thrive. The living is a perpetual curacy, annexed to the vicarage of Llanavan-Vawr, in the archdeaconry of Brecknock, and diocese of St. David's, endowed with 800 royal bounty, and £200 parliamentary grant. The church, dedicated to St. Mauritius, consists of a nave and chancel, both lately ceiled, and is remarkable for its diminutive size, being less than thirty-five feet in length: it stands just above the road side, and differs in its appearance from a neat cottage in no other respect than in having a small belfry near the west end of the roof. The average annual expenditure for the support of the poor is A 14. 5.
