That last photo is of the monument over Karl Marx's grave. I didn't realize that he was buried there before I came and was pleasantly surprised to find it there as I wandered around. I was really disappointed at how overgrown and ill maintained the cemetery was. Many of the tombs were illegible because of the extensive amounts of ivy and moss growing over the stones. In some cases, trees had overtaken the grave markers.
Finally, here are two photos that I took that I really liked and wanted to share. The first is at a tube station in London. I thought it looked particularly interesting in black and white. The second is of a moss flower and a lady bug (or as the British say, a Lady Bird). I hope you enjoy them as well!
