The Sea Level Rise Initiative is fighting to keep history above water.

Before Portsmouth was settled, Puddle Dock was a tidal estuary. By 1900, the inlet had been filled in to create additional land for the city’s growing populations. Now the sea is returning.

Four of the Museum’s historic structures — the Shapley-Drisco-Pridham, Sherburne, Lowd, and Jones Houses — are extremely vulnerable to sea level rise and are experiencing deterioration due to salt water infiltration during storm surge and astronomically high tides.

As a member of an advisory committee for the Climate Change Vulnerability Assessment on Historic Portsmouth, Strawbery Banke has joined with the City of Portsmouth to seek a solution to this increasing threat and on educational and awareness efforts including the creation of the Water Has a Memory: Preserving Strawbery Banke and Portsmouth from Sea Level Rise exhibit and hosting the Keeping History Above Water national symposium in May 2023. Additionally, the Museum is the focus of a University of New Hampshire study examining the vulnerability of coastal resources.

Philanthropic support plays a key role in saving these buildings and in continuing the public awareness efforts showcasing how science and history work together in the services of preservation.
