Panagia Church sits in Kavala's old Panagia quarter, the hilly peninsula where the city keeps its most atmospheric lanes and views. The church is not a blockbuster monument, but it belongs to the walk that makes this part of Kavala worth your time.
Use it as a marker while exploring the old town rather than as a stand-alone destination. Around it you get the mix that defines Panagia: sea views, steep streets, traditional houses, and the layered Greek and Ottoman history of the port.
