I can’t seem to find it on the web, but one candidate site (no idea which one) produced masses of human bones during some excavation — possibly Cuttles Mill.
Anyway, however, sidebars:

[snip] Locating the Final battle ...A further piece of evidence that I wish to consider in support of my thesis is the siting of a substantial building south-east of Arbury Banks. This building measures c. 150m x 115mm (Fig 5) and following a review of the building’s position, layout and size, these indicate the site of a probable temple (correspondence 2000), contrary to St Joseph’s initial interpretation of a farmstead (1977 160 & Plate XVII). The construction of a temple to mark the location and victory of the XIIII/XX would not be unreasonable. Only a survey of the site and excavation of this building will confirm its function. [/snip]
