Although the value and importance of public archaeology is recognized, most excavations and fieldwork are still conducted in Taiwan out of the public eye. The 2019-2021 Hepingdao project field seasons sought ways to include public engagement from the beginning of its mission. As the only archaeological evidence of the Spanish colonial history in Taiwan, Hepingdao is an essential piece of historical heritage. However, the team did not envisage how popular the excavations would be to the general public. The excavation was visited by thousands of visitors: including people living on and next to the island, local and international journalists, documentary workers, artists,  students, tour guides, local heritage volunteers, creating various dialogues next to the trench. The local government also played a significant role in promoting the site, making the project a laboratory of public archaeology in Taiwan. This presentation focuses on the negotiations between archaeologists and various stakeholders, the relationships between archaeology and the public, the meanings and importance of a European colonial site, and the advantages and costs of media for archaeology in modern Taiwan.
