What can occupy this space?

Just bought a house that is about 70~ years old. I have no idea about the idea behind these spaces when the kitchen layout was set. Please help me finding good use to this space.

The space for the first pic with the dog bowls is 30 inches wide and 62 inches tall. The space with the stove is 42 inches wide and 61 1/2 tall.

Also why did the previous owners left such a wide gap for the stove?🥲
