This is a walkway/road by the church in Ravello - do you see how the trees have been pruned back so that they will form an arch in the summer, but not get too big?
Here's a close-up:
And look at this one from the garden of the Villa Rufalo:
And there was a whole avenue of flowering trees leading to our flat. They were quite remarkable because in places so much had been pruned that the flowers were growing right on the stem.
Look at this tree from the main square of Ravello - totally reshaped by the hand of man.
There were many other instances of pruning - roses pruned waaaaay back and pergola structures like this one, with vines pruned to create shade in summer.
So we talked about pruning the whole trip - it was probably our most frequent conversation after the one 'OMG isn't that beautiful and look over there.'
