Welwyn Archaeological Society
This year’s Festival has a History Theme – from our ‘Horrible Histories’ parade to Tony Rook’s annual talks. As part of this year’s theme, the Kris Lockyear of the Welwyn Archaeological Society will be giving a talk – ‘Verulamium Revealed’. This will provide an account of the first complete geophysical survey of the Roman town of Verulamium – better known today as St Albans – and the discoveries made. For a fascinating evening, please join the Society at 8pm on Friday 23rd June in the Small Hall at Welwyn’s Civic Centre.
Since 2013 a group of volunteer archaeologists drawn from local archaeological societies across Hertfordshire, Buckinghamshire, Bedfordshire and Essex — including the Welwyn Archaeological Society — have been undertaking a series of geophysical surveys of the Roman city of Verulamium. The talk will firstly briefly introduce, in a non-technical fashion, the various methods used by the group, and what sorts of things they can detect. An explanation of how to “read” the images will be provided. The talk will then discuss what these surveys have revealed which include wealth of buildings, roads, kilns, ditches and pits across the city providing us with a much fuller picture of the town plan than previously. The group has, for example, located the town’s aqueduct although, like all Romano-British examples, it is more muddy ditch than Pont du Gard. The group has now completed magnetometry survey of the vast majority of the available area of the town, some 66 hectares. Since 2015 the group have had access to a Ground Penetrating Radar which is especially good at detecting the walls and floors of stone buildings. This survey has complemented the magnetometry survey which is generally better at detecting pits and ditches. The talk will conclude with ideas about what we have learned, and what we should do next.
