Yeah, this one isn’t in Shaw but it is Truxton Circle adjacent.
Eckington Presbyterian was an all white church that disbanded in the mid 1960s rather than integrate. It’s listed address of North Capitol and Florida Avenues don’t really help with figuring out where exactly the church sat. Thankfully the survey says it sat on Square 3516 on lots 116, 117 & 800. Unfortunately, those lots seem to no longer exist, so I’m going to say it is where the NY Pizza place stands. That’s my best guess.
In the survey it does not mention the racial make up but from other sources, it was a white church. It was also mainly white collar families who lived elsewhere in DC. Only 4% of the 290 members lived in the urban renewal area.

As I recall reading elsewhere, this church refused to integrate or sell to black congregation; they sold to someone who tore it down instead. It appears in some of the historical photos of Truxton circle.
