Belfast where the Titanic was built and they have a big and very modern Titanic museum very well done. This was a prosperous city until the “Troubles” began, it is still a work in progress, 14 peace walls divide various neighbourhoods. The battles are now fought with flags and murals. The police still drive around in their armoured vehicles.
It is clean and organised and has a very good Metro bus system with frequent buses and a 3.20 pounds all day ticket, a single fare is 1.90 pounds. Look out for the Hop on-off bus companies there are a number of them and the one I chose (Allen’s) had only one bus that took 2 hours to do a circuit which meant that if you got off the bus at a stop it would only be back in 2 hours.
