Seamus Heaney died in 2013 but there is a very lively Heaney Center in Northern Ireland, which you can visit virtually here.
And here, you can listen to him read 'Punishment'.
The BBC (always a treasure trove!) has produced this excellent 4-part programme on Heaney. A must-listen!
To study North, we will need to steep ourselves in history, both recent (The Troubles) and long past (Tollund Man).
Here are a few useful links :
The Silkeborg Museum, home to Tollund Man
The Viking Ireland exhibition in Dublin
