Unfortunately time and money availability forbids organising of National Field trips as back in the day with Cofiwn, but the below provides good info for communities to organise their own field trips and in such case there is no need for pointless flag waving (and otherwise purposeless patriotic boastfulness).

18 Ionawr: The Revolt of Llywelyn Bren 1316
6 Mawrth 1406: The Death of Hywel Gwynedd.
