The Temple of Athena Alea at Tegea is one of the most important temples constructed in the 4th century BC in mainland Greece. The architecture of the 4th-century marble temple was studied in detail by the author in the 1990s and the current project at the site aims to test whether new three-dimensional documentation methods can be used to settle the open issues in the design and construction of the temple. In 2016, aerial photography, reflectorless total stations and photogrammetry were used to document the archaeological site and produce a detailed georeferenced three-dimensional model of the temple. In 2019, the column drum repairs of the temple were modelled with photogrammetry to compare the documentation and reconstruction drawings made in the 1990s with the new digital models. The advantages of current three-dimensional methods are speed of documentation and very high accuracy in capturing the dimensions, geometry, toolmarks and textures of the architectural repairs.
