However, historical monuments from the past to the present have been subjected to many destructions, natural or unnatural. Thanks to advances in technology, it is easier to document historical monuments using digital photogrammetric methods. Today, we see the methods used in documenting historical artifacts as traditional measurement, laser scanning, and photogrammetric methods or combinations of them. In this study, historical artifacts were tried to be documented through close-up photogrammetry methods, which is a sub-working area of photogrammetry, through images taken with non- metric cameras of smartphones that we use frequently in our daily lives. Planned geodesic measurement and photography should be done in order to perform three-dimensional (3D) modeling with close-up photogrammetry. During the study, the checkpoints were measured using geodesic methods on the historical monument and part of it was reserved for accuracy analysis. The tomb of Fakih Dede in Konya, which is an important point of visit in the region has been chosen. 1. Introduction Cultural heritage has taken an important place in the culture and creativity of a society. Cultural heritages can be classified as public goods with their features (Yılmaz et al., 2000; Korumaz et al., 2011). Cultural and heritage properties provide certain benefits to the areas in which they are located, although there are not enough public resources for their maintenance and protection (Yakar et al., 2005; Alptekin et al., 2020; Polat et al., 2021a). Culture not only promotes economic development but can also be used as a means of transforming certain geographical areas. It, therefore, forms part of many local and regional economic development strategies (Alptekin et al., 2019; Polat et al., 2021b). Unfortunately, historical artifacts have been exposed to aging, humidity, dust, pressure, etc. over the years. They are exposed to irreversible deformation and damage caused by human beings as well as physical factors caused by the natural environment (Castellini et al., 2008; Lopez-Aparicio and Grašiene, 2013; Varas- Muriel et al. et al., 2014). Therefore, historical artifacts must be documented in order to be passed on to future generations. Documentation studies can form the basis for restoration projects of historical artifacts that have undergone deformation (Şenol et al., 2021). Up-to-date and accurate information about architectural and structural features, geometric shapes, and materials are the most important bases for the restoration of historical monuments (Yakar et al. 2010). However, the original architectural drawings necessary for the restoration of historical monuments cannot be found or are of low quality. Therefore, it is vital to document historical artifacts and monitor their displacement and deformation (Şenol et al., 2020; Kaya et al., 2021; Sužiedelytė-Visockienė et al., 2015). The measurement of a structure with traditional methods is a costly and time-consuming task. Especially the high
