After a lot of umming and ahhing I finally came up with an image I liked for the top banner. The default one was okay but not quite what I had in mind. Eventually I found an image of the precariously situated Civita di Bagnoregio, Viterbo.
This ancient town sits on top of a volcanic tufa whose crumbly nature has put the inhabitants in constant danger of losing their houses. Plans are afoot to reinforce the cliff face and preserve this spectacular site that guards the Tevere Valley below.
Many buildings have been destroyed over the centuries, both through erosion of the hillside and earthquakes and visitors can see the remnants of old cellars, stairways and drainage cut into the disintegrating rocks.
The drawing is for sale, measuring 30cm X 10cm and executed in pen and ink. Although I will retain the right to use the image as it forms a part of the website.
