Ahh, that's what I suspected, something terraced, and you planted it so well! I too love going back through my older pictures to see how far we've come, I started my garden here in 2011 and it's sure filled in fast!
Thanks for sharing and obviously you get more rain there than we do, everything so richly green,
I have cousins in Switzerland and Germany and was so amazed and the greenery and gardens when we visited in 2009.
