Tadao Ando regards his work as contextualist and emphasizes that his existence is only a part of the relationship between the history of architecture. This attitude is most evident in his work on the theme of revitalization of old buildings. Here, Ando pays respect to the time that has been engraved on the existing building and expends a great deal of energy in preserving it as a memory, while at the same tim eattempting to create a completely new contemporary space within it. lt is hoped that the dialogue between the old and the new evoked therein will have the power to connect time from the past to the future. The two sets of works introduced here are at the forefront of ANDO's architectural genealogy brought by the "dialogue with history"!
