Nicodemus Knob

Nicodemus Knob is a 30-foot limestone pillar standing on the eastern coast of Portland, marking the site of a former Admiralty Quarry. The column rises from open ground and offers views across the surrounding landscape and toward the sea.

The column was formed between 1849 and 1872 during intensive stone extraction for harbor breakwaters, when prisoners from the local establishment reshaped the landscape. This period profoundly altered Portland's entire geography.

The name comes from local stories about an Irish man named Nick O'Demus who arrived in the region after historical events. The pillar today marks a landmark that connects visitors to the human tales tied to this quarrying landscape.

The site is accessible by walking paths that lead across open ground with clear views of the pillar. Visitors should be prepared for changing weather and wear sturdy footwear, especially if the ground is wet.

The pillar serves as a natural benchmark showing how high the original ground level stood before millions of tons of stone were extracted. This makes it a unique record of landscape transformation that few visitors realize when they arrive.
