Penallt is a village in Monmouthshire, Wales. In the centre of the village, by the village green, is the seventeenth century village pub, the Bush Inn.
Nearby, the Penallt Old Church Wood is a ten acre nature reserve managed by the Gwent Wildlife Trust. This deciduous woodland forms a habitat for Pied Flycatchers, Nuthatch, Tree Pipits, Treecreepers and Sparrowhawks, as well as plants such as Wild Daffodils and Moschatel.
The Old Church is about a mile north of the village, and is mostly late mediaeval. The door bears the date 1539. The Church dedication is unknown, though there is a local tradition that it was St James, the patron saint of pilgrims.
The Argoed, a seventeenth-century mansion, lies to the south east of the village. It was once owned by the father of Beatrice Webb, the British socialist, economist and reformer.
The Wild Daffodil occurs in several places in Monmouthshire, such as Springdale Farm and Penallt Old Church Wood. However the greatest spectacle is provided by the slope below Margaret's Wood reserve, on the way to Whitebrook, where a carpet of thousands of flowers provides a wonderful display at the end of March and beginning of April.
