Northwest Greece has always been relatively isolated from the rest of the Greek mainland and, with the exception of small pockets of intense development on the coast, is still little visited by foreign tourists. Modern guidebooks of necessity concentrate on the few important classical and Hellenistic sites with only passing reference to medieval and later fortifications. Yet these monuments bear witness to the complex later history of the region when Norman, Italian, Angevin, Serbian, Venetian, Turkish and Albanian invaders competed for control. This book is intended to redress this imbalance by providing a detailed guide to a selection of the castles and forts of the area dating from the early Byzantine period to the eve of the First World War.
