15km south of Riga is an ex-concentration camp (now memorial). It was a little creepy - the inscription as you enter the memorial says "Beyond these gates the earth groans." Taken from a poem by a Latvian, its meaning is reinforced by the slowly-beating metronome embedded in the long slab of granite. It gives you the sensation of a heart still beating, or a person still working. Moving, interesting.

Seeing things like this make me feel empty, I question how man can be so cruel to another man. I don`t suspect I will find any deep philosophical comments here through this forum, but I can certainly say I was not prepared for the way it made me feel.
