Mill Pond II
At the beginning of the 19th Century, Boston found itself busting at the
seams. City planners decided to fill in the old Mill Pond in order to build
housing lots for working class citizens. The pond had also become dirty
and stagnant, posing a health risk to Boston residents.
So how did they fill the entire pond? Gravel from the central peak of
Beacon Hill actually ended up as Mill Pond fill. The map above from
1800 depicts the Mill Pond right before the filling process began.
The process of filling the pond lasted from 1807-1828.
