Idea for a map?

Blurry old photo based on celtic art. I’m trying to decide what patterns and textures I can use to create a map for college. I’m thinking of using photoshop to turn something like this into a maze / map?

Next step will be to upload it and try and change the colours and sharpness. Also to work out a route and decide if there will be celtic or saxon patterns. Will there be a treasure trove of coins or ornamental armour?
