Angelokastro (Greek: Αγγελόκαστρο) is one of the most famous historic sites in Corfu, and one of the most important Byzantine fortresses in Greece. It is located near Paleokastritsa and is built on a rocky hill. People watched the sea for enemies and warned other points of the island by beacons. The castle never fell, despite frequent sieges and attempts at conquering it through the centuries. The fortress has now been renovated and worth a visit.
You will reach Aggelokastro from Krini village, by following the signs. There is a parking lot. Be prepared to walk up the hill for about 20 minutes, but the panoramic view on top of it, worth it. A church dedicated to Archangel Michael is located at the highest point of the southern side.
Tip: After 18:00 it’s closed but people can still go there. The panoramic sunset is amazing, but there are no lights, so be careful.
