Removed wallpaper - what is this?

[vanitabarrett]

I'm in the process of removing wallpaper from the living room so we can re-wallpaper. Doing so, I've discovered a 1-2cm line running horizontally along the wall, about 1/4 of the way down - does anyone know what this could be?

Possibly where a picture rail or plate shelf had been fitted in the past.

Yes old picture rail been removed very common about 18" down from the ceiling as a rule.

Definitely some kind of dado rail if picture rail is the proper term for it. Either paper back over or replaster the wall

Great, thanks everyone!
