This paper presents the meta-functional typology of the forts of Kaunas Fortress as the unique architectural-urban objects that can help to create a more preferred, legible and complex cityscape. Space syntax analysis methodology is applied for the analysis of the forts. Two aspects are investigated. The first one: location of the forts in the axial map of Kaunas is considered while evaluating depth, global integration, local integration and other features of the map. The second one: structure of convex spaces of the all 10 remaining forts is analysed in terms of the depth, “here and there” relations, serial vision, etc. Significant changes or destructions of the original plan of the analysed objects are considered as well. Meta-functional typology of the forts in terms of contemporary architecture is offered. The results of the investigation are significant for the utilisation of the forts within the contemporary urban context.
