As stated by a couple previously, photography is about light. If the light is right, any subject can be interesting whether landscape, cityscape, or whatever. Try getting out early or late in the day when the sun is lower. Side lighting creates powerful images with shadow and light perfect for B/W photography. Then look for strong compositions that compliment the lighting. You don't have to have a subject in mind when you go out to shoot. Your eye will see if the lighting is interesting and that's what you shoot. Good luck.
