Secret - and not-so-secret Gardens

Although the cities are quite full of people and buildings tend to be squished very closely together, many find ways to fit a garden into their world.
This is on the grounds of the Oxford campus. Ok, how cute is THIS? Taken on our loooong (and all uphill) walk to our youth hostel in Bath.
The best part is, there's no litter box to clean ;)
In the tiny town of Lacock, the back garden of a store. Ok, I had to sneak through a gate and tiptoe into the back but it was worth it, yes?
I loved these little below-sidewalk level gardens in Edinburough! Especially since the buildings in this area are all the same gray stone. Then, you'd look down and see these charming private spaces just below your feet!
Even on a houseboat in Amsterdam, you can find a bit of green! Note the fountain in the foreground (right) and wooden shoe in center back - filled with 'hens and chicks'.
