Atocha station, Madrid.

The circular structure at the left is a memorial to the victims of what is known here as 11-M, the 11th May, 2004 bombing of three commuter trains entering Atocha in the morning rush hour. 193 fatalities and over 2,000 injuries were the horrific result. The 11-M monument is simple and moving and it has the names of the fatalities in plain but beautiful calligraphy carved on the inside of the circular monument. You can only enter from within the station and it can be hard to find but worth it! I can't remember now whether I didn't take photos because they were forbidden (always possible in the most unexpected places in Spain) or because I didn't yet possess a camera. Possibly both! I need to re-visit.
