Reuse of the historic monument is a new way of preserving the historic site, the expression of the historical situation is a kind of method to regenerate the historical status. The reuse of historic monument means that by applying a new usage or a new value system, the historic monument or traditional architecture and its facilities will be no longer detached from our daily life, but can meet the need of the era.Historical situation is the re-presentation of historical events, by means of visual and hearing stimulation, through which people can experience the change and progression of time and space. In other words, by using multimedia, the “one dimensional” historical events become “three dimensional”; so it helps people not only back to the past, but may have interaction with the ancient person, event, time, and space.This study is taking Taiwan Yamen of Treasury and Civil Administration of Ching Dynasty as an example to illustrate the regeneration of historical situation. The building was put aside initially because of aging with wearing out, but afterwards because of postponement of remodeling. According to the design of Taipei Department of Cultural Affairs, it is supposed to be reused as a tea-house, with traditional architecture and Chinese Music, to present the beauty of our culture. If we could make use of its distinguished historic background --- the only left architecture of Yamen in Taiwan, and dress up with regeneration of historical situation; then the historical monument would become more meaningful and valuable to history. At all, it would be a model for the preservation, maintenance, and reuse of historical monument in the future.
