North and mid-Wales are rich in history. Caernarfon is a Royal Town and has a small harbour with beautiful views across the Afon Menai to the south of Anglesey. Caernarfon is perhaps most famous for its dominating castle. Constructed in 1283, it was built not only as a defence but also as a seat for government and royal palace. It is easy to see how this majestic construction combines all three of its functions. The castle was designed to echo the walls of Constantinople and its majestic architecture still dazzles visitors to this day. Builth Wells is at the confluence of the River Wye and River Irfon. It hosts the Royal Welsh Show at the Royal Welsh Showground.
