For the next few days I will go through the list of new(ish) Anavasi Topo Islands maps. At least some of the maps should be available through Amazon, I will start putting up “[Buy!!!]” links also. Otherwise you can try Anavasi’s own Shop. First out is Chalki:
Quote from the publisher:
“A tiny island though very rich in monuments and ancient remains. More than 50 byzantine chappels, dozens of rock carved cisterns and old agricultural settlements and a well-preserved medieval caslte with a ruined medieval settlement at its foot. The new detailed map by ANAVASI will be your precious guide to discover all these little known remains, most of them accessible only by footpaths.”
