A collection of construction documents from the Joseon Dynasty has been registered under UNESCO's Memory of the World program.

The "Hwaseonguigwe" depicts the construction of the Hwaseong fortress in Gyeonggi Province.

The U.N. organization's International Advisory Committee decided during a meeting in mid-June to recognize the documents on its global cultural heritage list as of July first.

The documents were published in 1801, five years after the Hwaseong fortress was completed. It describes details of the construction work including plans, progress reports, cost breakdowns, names of the builders and the number of construction days.

As a result, Korea holds a total of six collections with the international designation including the Hunminjeongeum, the Korean writing system, the Joseonwangjosillok court journals of the Joseon Dynasty, and the Tripitaka Koreana from the Goguryeo Kingdom.

UNESCO's Memory of the World International Register is a list of library and archive collections of global significance. It was established in 1992 to preserve and promote pieces of documentary heritage that are of universal value.
