Boston's history is tied to the sea, whose smells and sounds once pervaded the town. The Walk from summit to sea, spanning one mile and descending 100 feet, brings that history to life.

Mayor Thomas Menino dedicated the Norman B. Leventhal Walk to the Sea in 2008.

These “growth rings” are meant to recognize mankind’s connectivity with nature and the trees, to celebrate the cycle of life, and to foster harmony within the landscape of the park.

The project was produced by Now + There, designed specifically for this site by Oscar Tuazon, and guest curated by Pedro Alonzo.
