It is possible that the site was referenced in the diaries of
Nicholas Blundell on 28 September 1721, when he noted "a place in [Francis Farrer's] ground where 'tis supposed there formerly stood a small Castle". The site was identified in the
Tithe map of 1846 as 'Castle Field', likely with reference to its history as a former Roman fort. Subsoiling activities in 2003 during construction work and field walking in 2005 suggested the presence of a large sandstone structure. In 2013, the
stratigraphy of the site was investigated, revealing a complex history of multiple phases of inhabitation and further archaeological evaluation of the site in 2014 and 2015 revealed the presence of a fort, including a buttressed structure resembling granaries found at other Roman forts in Britain. In 2018, the presence of a fort of at least two phases was confirmed by an
electrical resistance survey, and in 2020 an assessment by
Historic England using
Google Maps and
Lidar imagery showed that the fort was visible as crop marks, soil marks and earthworks. The site was given
scheduled monument status by the
Secretary of State for Digital, Culture, Media and Sport status in 2020. ==See also==
