The Keystone aims to preserve and revitalise keystone culture. The project selects and analyses the symbolic meanings of keystone culture by examining its manifestations at different times in history. Through this process, the project seeks not only to understand the traditional meanings of keystone culture but also to infuse them with new meanings through an abstract and iterative approach. Ultimately, this cultural heritage is combined with contemporary architectural design to create a cultural expression that honours tradition while embracing modernity.

Architectural styles and decorative elements in different regions reflect local cultural characteristics and identity. In some cultures, a particular style of sculpture of a human head may be a reflection of a local tradition, demonstrating local artistic techniques and aesthetic concepts. These sculptures also have historical and educational value. By studying the style, subject matter and production techniques of these sculptures, one can learn about past artistic genres, skill levels and cultural backgrounds.

The sculptures on the keystone are also a communication tool, conveying messages and stories through art forms. For tourists and scholars, they serve as a window into local culture and history, promoting intercultural exchange and understanding.

Today's modern architecture has neglected the cultural lineage for the sake of efficiency and cost, and it is also a kind of alienation from the history and traditional craftsmanship. If this is still the case, in the future, architecture will only be a tool to provide places for people, it will not be able to bring more meaning. These traditional artefacts and architectural styles are a bridge to the past and can lead to a superficial understanding of history and cultural heritage.
