Cultural heritages are the history of the nations, and history forms the identities of the nations. Therefore,protection of cultural heritages means protection of the history and identity of the nations. Identification of the currentstatus of cultural heritages is important for documentation, preservation, and for use as a base for restoration.Documentation studies need robust and scientific methods. GIS and photogrammetry have recently been the mostcommonly used scientific methods for documenting cultural heritages. The aim of this study is investigate thephotogrammetric method and GIS for documentation of cultural heritages digitally. In documentation studies, digitalterrestrial photogrammetry is one of the main methods of processing information of historical monuments on computersaccording to GIS and documenting it in three dimensions. In this study for documentation, all data of 46 historicalmonuments located in Silifke/Mersin were collected and transferred to a database so that it is made queryable. Some ofthose heritages were reconstructed as 3D models by the use of photogrammetric techniques. Finally, 3D Models wereintegrated into the system for presentation.
