The importance of construction for the Joseon state is reflected not least by the abun-dance of buildings which are today designated as cultural as well as world heritage sites. However, this importance is belied by the scarcity of sources concerning their construction. In contrast to the Chinese case, manuals that explain and pass on the modes and templates for the construction of specific buildings are missing. The only comprehensive sources that deal with a selected number of these construction pro-jects seem to be the uigwe 儀軌 (Ritual Regulations). A meaningful approach to the seemingly contradictory Korean context was provided with the development of a framework of a general history of architectural knowledge by Jurgen Renn and Matteo Valleriani. They examined the importance of architectural knowledge in terms of practical and theoretical knowledge with respect to its written documenta-tion. This general framework offers explanations for certain developments in Korean history within the context of the development of architectural knowledge and the carrying out of construction projects as documented in uigwe. This article analyzes the content of representative uigwe on construction projects against the backdrop of this historical framework. It shows how the genre was rather ill-suited for the pur-pose of a manual for construction projects and the way in which the Hwaseong for-tress construction project can be regarded as an exception to this. It further explains how the development of architectural knowledge in Korea in general as well as the exceptionality of the Hwaseong project can be understood and located within a world-historical framework.
