putting stuff on the walls when you have a plate rail

So, moved into a new apartment – in a historic (1911) building. It’s beautiful, but the original wood presents a problem. How on earth do we put stuff up on the walls (prints, framed photos, etc) when we have a plate rail? The rail is at 80 inches from the floor (see photos below) in the living room. Do we put stuff below? Above? Below and above? Help!

these are before we moved in.

and here it is now that we’ve got furniture in it!
