Event/Activity EPM93 - Archaeological watching brief on the extension to the Frewen Library, University of Portsmouth, Hants

Watching brief undertaken on the groundworks for an extension to the University of Portsmouth Frewen Library. Observations were made on machine excavated ground beam trenches and other foundations. The site of the extension was believed to be on or near the site of a section of the Portsmouth town defences dating from the 1660s. The defences were demolished in the 1860s and 1870s. A watching brief nearby at Ravelin Park Car Park in 2004 (Old Student Union EPM95) had revealed elements of the East Ravelin and Town Mount Bastion. A large feature, interpreted as the outer moat of the post 1665 fortifications was revealed, as were other features probably related to the outermost defensive line of the same date.
