Ol' Coal

I haven't posted in a while, not much new to share, except piles of boxes. I was walking the dog to the back yard and thought these old coal thingies would be neat to share. The house has two. One larger one labeled Majestic down the side ally and a smaller one at the opposite side of the house near what appears to be an old chimney for a coal burning furnice. I am not really sure what to call these openings. Hatches maybe? I tried googling with no luck. So if you know, let me know. Thanks
