This study is intended to clarify the phenomenon of re-utilization of historic constructions in Milan. To investigate the characteristic of adaptation for the public use, this paper focuses on the spatial composition in the re-utilized monasteries. Analyzing typologically the ways to arrange such spatial compositions, some continuity to compose new functions such as universities and museums are identified. Examining these continuities, the spatial composition for the public use appeared in the way to use the courtyards.
