After a few days in beautiful Donegal I travelled into Derry and Northern Ireland. I had not realised I was arriving on the day of the Apprentice Boys' March when tension was heightened.
Maybe on another day I would not have noticed things so much, but there still seemed to be trouble near the surface of this rather beautiful walled city. This huge tower has cameras trained all over the Bogside area.
There were a few vehicles burned out, and a few bonfires lit.
The murals on some of the Bogside buildings were very powerful and said a lot about the time of the Troubles.
