This is part of what was once 3700 acres of the Hingham Naval Ammunition Depot that produced ordinance including
rocket motors and mines during WWII. There are a few areas still cordoned off limits as they may contain UXO, Unexploded
Ordnance and or some topsoil contamination and other hazards. Of the more than 110 underground bunkers, only a
handful remain visible. Careful inspection can still reveal evidence of Explosive Ordnance Disposal (EOD) at the burning
grounds remediation recently. Torpedoes were even tested in one of the ponds. In the 1970's it was common to discover
disintegrating barrels of toxins, PCB laden transformers, bunkers open to the public and ordinance strewn throughout the
landscape. The restricted site is rapidly under demolition order and will likely be leveled soon. This site is very dangerous
and exploration is ill advised.
This WWII ammunition
base is now part of
Wompatuck State Park.

This one of the assembly alcoves that were on the railway. It is
heavily laden with asbestos, barbs of rusted metal and broken
glass. The graffiti strewn walls are signs that the site was left in
an unguarded and unsafe status.

detonator and a .223 practice round, safe and expended.
You still never know what you'll find at Wompatuck. Most of the bunkers have been backfilled and cemented shut. A careful
and cautious explorer can still locate interesting sites. This bunker is behind building #51as indicated in the above photo.
The vent has been compromised as shown in the middle photo. The mosaic on the right was a risky one to capture. It is
essentially the entire undisturbed bunker.
Some of the dangers of wandering in the dense woods is
the random placement of razor wire. The undergrowth of
briar's are natures match to this man made weapon of war.
Evidence of the safety measures
once in place are diminishing but
are still visible if you look carefully.
These blast proof doors once
were in place to prevent a chain
