Berriew () is a village and community in Montgomeryshire, Powys, Wales. It is on the Montgomeryshire Canal and the Afon Rhiw, near the confluence (Welsh: aber) with the River Severn (Welsh: Afon Hafren) at , 79 miles (128 km) from Cardiff and 151 miles (243 km) from London. The village itself had a population of 283. and the community also includes Garthmyl Hall and Refail. Buildings and architecture Berriew contains many architecturally important buildings. There are 103 Listed Buildings in Berriew of which 5 are Grade II*. Nearly a quarter of the listed building are connected with the Montgomeryshire Canal which runs across the parish to the S.E. of Berriew. The most important of the listed buildings are Vaynor, which is probably the earliest brick built house of the mid-17th. century still standing in Montgomeryshire, and Glansevern, designed by the notable Shrewsbury architect Joseph Bromfield in the Greek Revival style and probably the best example of his work. There are two important timber-framed houses, the Vicarage which is dated 1616 and Lower Cil Farmhouse. An illustration of the Vicarage was used to illustrate the dustwrapper of the 1st edition of Peter Smith's important book on Welsh Vernacular Architecture ‘'Houses of The Welsh Countryside'’. Another notable house is Garthmyl Hall, Berriew, which is by a leading 19th century designer and architect James Kellaway Colling. There are also a number of other larger houses in Berriew which include Brithdir, a timber-framed house which was considerably extended in the early 19th century; Pennant, a fine early brick house built in 1755; Rhiewport, a Regency house that is also probably by Joseph Bromfield, and Trwstllwelyn, a house with much early 18th century brickwork. A sad loss was the fantasy Gothic villa of Bodheilin in Brithdir township, which was burnt down in 1906. Timber framed and Cottage Ornée houses Rather than the individual houses, Berriew is best remembered for its half timbered cottages which cluster around the churchyard and along the banks of the river Rhiew. There are further examples in the township of Refail. These can probably be attributed to the architect Thomas Penson. In the late 1830s, at the same time as Penson was working on remodelling Vaynor Park in Berriew for John Winder Lion-Winder, he was also remodelling and building houses in Berriew for the Vaynor estate. As a result of his work Berriew developed as a village with many attractive Cottage
