Here is Thursday Doors from Norm at Miscellaneous Musings of a Middle-aged Mind (https://miscellaneousmusingsofamiddleagedmind.wordpress.com/2017/02/02/thursday-doors-february-2-2017/)

We exposed the brick on one of our chimneys in the basement (to finish installing the gas fireplace in the dining room) and found this little door.  When we (finally) refinish the basement, we are likely going to expose all the brickwork ’cause it’s too pretty to cover up!!
