Note 738 — Chapter VII · THE CASTLES OF THE NORMANS IN ENGLAND (continued 3)

“In burgo de Walingeford habuit Rex Edwardus 8 virgatas terræ; et in his erant 276 hagæ reddentes 11 libras de gablo.... Pro castello sunt 8 destructæ.” D. B., i., 56. If we divide these 276 haughs by the 114 acres enclosed by the town rampart, we get an average of about 1 rood 26 perches for each haugh; multiply this by 8 (the number destroyed for the castle) and we get an area of 3 acres, which is about the average area of an early Norman castle.
