This massacre occurred in the 1870s, and the shadow we can see today is just a round shape like a manhole cover built with leftover bricks from some buildings at that time.
This place is actually a large park now. Regarding the traces of the massacre, there are only a few small spectacles that do not know whether they are true or not. If you are interested, you can take a look. I am not very interested.
Interesting place, you'll get there by walking the freedom trail.
The site of the Boston Massacre is marked by a large circle in the cement; otherwise, there isn't much here.
