In "Strolls through Italy Volume 5", Gregorovius continues his illuminating journey through the lesser-known corners of Italy. This particular volume focuses on his explorations of the Apulia region, situated in the heel of Italy's boot. Gregorovius acts as an able guide through the region's Byzantine, Norman, and Swabian past, highlighting the architectural, cultural, and historical remnants from each epoch.
The central theme of this volume is the convergence of diverse cultures and the resulting synthesis that shapes regional identity. This is expressed through Gregorovius's in-depth exploration of iconic cities like Bari and Lecce, as well as his visits to rural areas and smaller towns, where he uncovers the vibrancy of local life and traditions.
