This paper aims to describe the state of cultural heritage sites in Manado City that are poorly maintained, damaged, changed in function, and the challenges of developing Manado city center as a heritage area. In developed countries, the old city area with historic sites is well preserved, even though the old building is located between modern buildings, people still appreciate it and tend to protect it from damage both by nature and by human hands, so that the site becomes a tourist attraction. However, this did not happen in the city of Manado, cultural heritage sites were damaged, stolen, and tended to change functions. Using the methods of observation, documentation, and interviews, the researchers examined the condition of several historical and cultural sites in relation to the development of heritage tourism areas.
