English: TOWN HALL. The last remaining Georgian Town Hall in Montgomeryshire. The red brick Town Hall forms a striking termination to Broad Street, although the centre of the building is offset to the north of the line of the street. Built by William Baker of Audlem, 1748-51, for Henry Arthur Herbert,  1st Earl  of  Powis, for whom, Baker had  also in 1745 provided designs for a new Town Hall at Bishop’s Castle. The original design of the Town Hall is shown in a drawing of 1784 by the Rev. John Pridden in the National Library of Wales . This shows the ground floor market space of the Town Hall open with five bay arcades.  Pridden  shows the central bay, facing Broad Street projecting forward  with a larger arcade arch and above this a lunette window. The upper floor which housed the Council Chamber and Court of Great Sessions and Quarter Sessions. In 1828 Thomas Penson, at the expense of Lord Clive, raised the roof level over the first floor and introduced sash-windows, rebuilding the pedimented  gable, but without the coat of Arms.  An extension was added at the  rear  with rounded quadrant corners and was tied in by extending the string courses around the building  and adding a matching pediment to that at the front. The arcade arches were infilled with glazing in 1887, The clock tower was added in 1921. The predecessor of this building was probably a  half-timbered structure,  which the Speed map of 1610 shows was sited, lengthways,  in the middle of Broad Street
