If your shots are typically of static subjects (no people in the old buildings), you'll have another big advantage. Your profile suggests you aren't presently using any lenses with VR. The 18-105 is a VR lens that will allow you to shoot at much slower shutter speeds than with the non-VR lenses you have now. That will allow you to use lower ISO values. Coupled with the dramatically better high-ISO performance of the D7000, I think you are in for a delightful experience!
