Stone wall c. 14th century

I noticed the various coloured stones in this 14th century wall/building during my walk this afternoon. The stones are quite different from one another in colour, shape and texture but yet are bound together into a wall - much like humanity in this world.

Each stone must have a story to tell - how far it travelled before it was set in the wall and how it has changed over centuries.

I haven't run out of ideas for blips - I did find this wall interesting :-)
