We are stopping in Belfast for a day. What should see when we are there?
What do you like?
Since we don't have a clue I'll suggest:
Black Cab Tour of The Troubles
The Titanic Museum
Crumlin Road Gaol
St George's Market
Remember Ireland is a separate country. Belfast is in N. Ireland which is part of United Kingdom. British Pounds instead of Euros. Might read up on The Troubles for some background.
