The Late Antique architectural remains on the acropolis of Koroneia’s city hill have not yet received the research attention they need in the current Ancient Cities of Boeotia project. This thesis will delve deeper into the collapsed vaulted ceiling remains that have been found on the acropolis and provides a thorough description, coordinate measurements and plans, and begins the difficult task op interpreting these remains. It is attempted to reconstruct what the building was and draw parallels to other similar buildings. Research into the remains was conducted in the 2009 field season by architectural specialist Dr Inge Uytterhoeven, and the August 2012 field season saw the continuance of this research by students. For a field school on ground-based digital recording techniques, students were tasked with recording the remains of the large structure on the acropolis which had earlier been dubbed the ‘Bishop’s Palace’ by researchers. Over 200 Total Station measurements were taken, detailed descriptions and sketches were made, and over the course of two mornings the entire remains were carefully documented. Also, suggestions for the improvement of fieldwork and analysis methods and suggestions for further research are made in this thesis. In this thesis, special attention is paid to the recording and analyzing techniques used, and these are described in detail. Also, an attempt has been made to interpret the remains and compare them to other, perhaps similar, complexes. In close consultation with Dr Inge Uytterhoeven, the remains have been roughly dated to the 5th or 6th century AD, the Late Antique period on the Greek mainland. A look at both the remains and the period suggests that the most likely interpretation is an elite villa or house with a public character.
