There is a mystery smokestack on Capitol Hill. You may have seen it behind St. Peter’s Church at 2nd and C St. SE. Below is an image sent to us by GoDCer Geoff a while back, asking what this smokestack was. If anyone in the GoDC community knows, please share your thoughts below in the comments.
Here is the satellite view from Google Maps. The smokestack is in the middle, behind the church.
Below is what the block looked like in the 1921 Baist map. I see now evidence of a smokestack.
