ALATA CASTRA(πτερωτὸν στρατόπεδον, Ptol. 2.3.13), in the territory of the Vacomagi (Murray and Inverness-shire) was the northernmost station of the Romans in Britain, and near Inverness. This fort was probably raised by Lollius Urbicus after his victories in Britannia Barbara A.D. 139, to repress the incursions of the Caledonian clans: but it was soon abandoned, and all vestige of it obliterated. (Capitolin. Antonin. P. 5; Paus. 8.43.3.)
