Petriana
Petriana a fortress in the N. of Britannia Romana, between the Wall and the river Irthing, where the Ala Petriana was quartered. Camden (p. 1020) identifies it with Old Penrith; but Horsley (Brit. Romn. p. 107) and others fix it, with more probability, at Cambeck Fort or Castle-steeds. (Not. Imp.) It is called Banna by the Geogr. Ray. (Horsley, p. 498.)
