I do very much enjoy castle walls with character, and this gatehouse by David Zambito fits the bill. The wall is textured, and the landscaping has a great organic look to it. It gives a nice sense of time: this wall has been here a long time and seen things, and so many stories have passed through it.
David has some nice examples of landscaping (check out this cobblestone road!) in his flickr gallery, and I invite you to take a peek!
