I think Allie that the Romans are so far back they have been almost forgotten. But it was just around the corner from here that they finally conquered englandandwales when they crossed the Straits and beat up the Druids.
The Normans/Orcs brutally conquered this part of the world with huge armies and their massive fortresses (Conwy, Caernarfon and Beaumaris) stand to this day as an un-ignorable reminder - along with their mediaeval towns where the locals were not allowed to live or trade. The local population near Beamaris were thrown off their land and made to live in a sandy waste on the other side of the island - Newborough is still a rather bleak little village and Beamaris more English than the rest of the island.
The Normans took all the best land leaving the damp, scrubby land for the locals.
In the 19th C one of the gentry spent his slaveryandslate money building himself the most enormous, vulgar, imitation norman castle at Penrhyn, just to rub salt into the wound. It's where I do my volunteer gardening and it is my nomination for the worst-taste-least-sensitive NT property. http://www.nationaltrust.org.uk/penrhyn-castle/ Photographs cannot convey just how flipping big it is.
Been reading the books by Sharon Penman on the normans and they seem to have been an extremely brutal, nasty bunch.
