I am an archaeologist (new to Blender) interested in modeling historic and archaeological sites. Can you import photos or videos to blender to build a model of an old castle?

You can also add a images/videos as rendered backgrounds andtrack the video movement to incorporate models into the video footage. So the answer to your question is yes
