|Cannons&Guildhall, Derry 2015|
I took a closer look at one of the cannons and found this plaque:
|400-year old cannons on Derry's walls|

Guildhall Square is used for concerts and open-air events. There wasn't much happening the day I was there, as you can see. As I don't like crowds I was quite OK with that - more on that subject tomorrow!
