We field surveyed 4 architectual spaces which are enclosed or surrounded by darkness, and estimated relations of their spatial images with physical design elements paying attention to darkness distribution and luminance contrast. We also examined relations by models in 1/10 scale. As the sesult, we have found that (1) spatial order images such as enclosure surrounding, expanding are created by placement and size of the openings which inflence darkness distribution, (2) atmosphere images such as serenity and vividness are created by luminance contrast which are created by exposed beams and columuns and by reflection of sun light on the floor, and (3) attractiveness of the spaces is created by combination of the spatial order images and the atmosphere images.
