Registered heritage buildings and sites are not just shapes and designs passed down from generation to generation. The materials and techniques used are part of the tangible and intangible heritage and contribute to the authenticity of the monument. This activity is a collaboration between the cultural heritage community of Semarang City and the City of Manila which visited Semarang. This activity aims to understand the authenticity of historical architectural works through their material and technical elements in Asia by comparing similar works in the cities of Semarang and the Philippines. It is hoped that the results of this activity will be able to find authentic images in several examples of traditional Asian architectural works and provide alternatives for forming place identities in both the cities of Semarang and Manila.
