Bow Bridge, Iwood
Bow Bridge is a Grade II listed stone arched bridge, that crosses the Congresbury Yeo at Iwood, a hamlet of Congresbury in North Somerset. The bridge is largely intact and dates from the early 19thcentury. It is constructed from local stone with a single span arch of approximately. The singlecoursed stone parapet is low in height and consists of a row of voussoirs and an unmetalled farm track. It is in close proximity to two other Grade II listed bridges to the east and southeast of Congresbury.
Etymology
The name "Bow" is a cognate of the Welsh word bwa "arch", both being derived from the Old English boga, "bow" or "arch". In West Country dialect, a "bow" is a name for a stone arched bridge that spans a river or rhyne. A "bow" can also refer to a river abruptly changing course.History
The bridge has been dated to the early 19thcentury but a more precise date has proved difficult to ascertain. Gradiometry and resistivity surveys at Iwood have found little evidence of mediaeval occupation. Furthermore, before 1814, there is an absence of cartography, apart from John Jacob de Wilstar's survey of lands for Queen Elizabeth's Hospital in 1739, that documented a limited number of land owners. However, the bridge does appear on the 1814 Congresbury enclosure map on lands held by Benjamin Thayer, a farmer at Iwood Farm, that had been occupied in the 18thcentury by James Wreach. In particular, the bridge is shown crossing Thayer's land north of the river at the River Ground, to pasture land on the south.On 26March 1810, Young Sturge and James Staples, the Commissioners of Enclosure for Congresbury, Wick St. Lawrence, and Puxton, invited tenders from builders and masons to build a bridge in the Great or New Moor, over the Congresbury Yeo. Edward Lukins, a mason at Yatton, won the tender, and together with Thayer, signed contracts with the commissioners on 23April 1810. The contract value was £280, a substantial sum when compared to average agricultural wages at the time of around £30 per year. In total, the Congresbury enclosure improved, or caused to be built, 398 bridges and gates, at a cost of £1,314. These enclosure costs were a burden for many landowners as they often had to sell part of their land, and less commonly, mortgage other properties, to meet the expenses imposed by the commissioners. Thayer farmed the land around the bridge until his death on Christmas Day 1860, and on 20February 1861, the farm and lands were sold at auction.
