The past is another country; but you can see it from here on a clear day

I took this picture, of what Americans might call a "Vacant Lot", today. It is a few streets from our office in what is variously known as "Anderston", "Glasgow's International Financial Services District" or "Glasgow's notorious red-light district" depending on the context.
I was amazed at the number of layers of history that you can see imprinted on these two walls, from the gable of the cottage apparently embedded in the newer wall on the left, through at least one layer of sandstone and two layers of brick. The brick isn't one age, if you look carefully you can see that it too has been extended upwards as this part of the city evolved. At the bottom of this page is a photograph of Anderston Village in the 1860's.
The "vacant lot" is down in the far right hand corner of this map near to the junction of West College Street and Brown Street, on the right of Brown Street.
Looking on Google maps today you can clearly see the space on the right of Brown Street north of the junction, but West College Street is now Crimea Street, and the MOD's Kentigern House sits across the top half of Carrick Street.
