Abstract
This study focusing on Norman Foster's museums tries to explain the aspects of harmony pursued between the interior/exterior of museums and the surrounding classical contexture while keeping to technological images consistently and tries to show its meaning in the contemporary museum architecture. The results of this research show that, although Foster's museums in three categories(new construction, renovation and extension) should be conceived differently, Foster always applied high technology and new materials to his museums while properly harmonizing traditional preexisting in moderate form, size and internal spaciality of his museums. The efforts to create something richer from both old and new have been thrown into his overall museum projects and Foster was able to maintain technological designs while fitting within classical contexts, both within and outside the building.
