Practical - yes.
Necessary - usually.
Inspiring - hmm.
Bordering the edges of gardens.
Propping up the railway.
Providing a turning point for the horses that used to tow the boats.
And entrances - now defunct.
Looking closer you recognise the variety of colours and textures.
The variety of plant life.
And plants provide habitats for creatures.
Where the man made starts to decay nature starts to thrive.
(Although the legacy of Tez still holds strong after thirty years!)
Life on the wall is perhaps not as overtly picturesque as the canal but on close inspection it is an incredible structure. It doesn't just fulfil it's practical obligations - it does so much more. I'm sure the original architect did not expect it to diversify in such a way - who could predict that something as hard and uninspiring as a brick could age and adapt to it's environment. But the wall has done just that. It is now host to an abundance of living organisms and the unexpected beauty which that brings.
Inspiring - definitely.
