Ursuline Monastery Stone Wall

I am a lover of old buildings. I am also interested in architecture. Unfortunately, my math is so poor that I have to use all my fingers to count. Hehe ....
This Cor Jesu or Ursuline Monastery wall photo was taken when the sun was completely covered by cloud. Just because it was in the mid day then my Sony Ericsson G502 was able to take the scene.
