Visibility Graph Analysis and Monumentality in the Iron Age City at Kerkenes in Central Turkey

Abstract

This paper investigates symmetry and visualization at two monumental gateways excavated in the late 7th–6th centuries b.c. Phrygian city on Mount Kerkenes (Turkish: Kerkenes Da?) in central Turkey. One of these, the Cappadocia Gate, is one of seven city gates piercing the 7 km stone-built defenses; the other is the Monumental Entrance to the Palatial Complex. We use visibility graph analysis (VGA), a branch of space syntax analysis, and viewshed isovists to demonstrate that a similar visual and symbolic conception underlay the design and furnishing of these two gates. Both were conceived to signal different messages to people entering and exiting the gates, and both manipulated the visibility of cultic statuary to achieve this effect. Other contemporaneous monuments, like the Midas Monument in the Phrygian Highlands, shared many of the same principles. VGA reveals fundamental characteristics of the experience of Phrygian monumental architecture and also indicates a degree of city planning.
