Locations: Caernarfon Castle, Conwy Castle, Plas Newydd, and Llanfairpwll
Nowadays a ticket or a day pass is more than adequate to gain entry into the magnificent castles at Caernarfon and Conwy.
But in the days of Edward I visitors were more likely to use flaming arrows, battering rams and giant catapults in order to appreciate the nuances of medieval architecture! But if you're after a location with a rather gentler history then try Plas Newydd on Anglesey.
This magnificent 18th century mansion located right on the banks of the Menai Straits boasts artist Rex Whistler's largest indoor wall painting as well as a military museum dedicated to the 1st Marquis of Anglesey who lost his leg at Waterloo.
Down the road from the aristocratic finery of Plas Newydd lies the name on almost everybody's lips - that's Llanfairpwllgwyngyllgogerychwyrndrobwilllantysiliogogogoch to you!
Aside from the name the main draw to the village is its train station - very first to be opened on the island - and a whistle-stop tour of the menu at Sidings restaurant is well worth the effort.
