Maine’s lighthouses have been recognized as endangered heritage sites due to threats from climate change, as noted by the World Monuments Watch. The 2025 list includes 66 lighthouses built between 1791 and 1910, many of which remain operational. The Gulf of Maine’s rapid warming creates urgent challenges, particularly from rising sea levels and intensified storms. Recent damages to notable lighthouses emphasize the need for preservation efforts.
Maine’s historic lighthouses have been added to a global list of cultural heritage sites facing significant threats, primarily due to climate change. The World Monuments Watch has released its annual list, which includes 25 sites at risk, highlighting issues such as neglect and natural disasters that affect their preservation.
The list features 66 lighthouses constructed between 1791 and 1910, with many still operational as guide beacons utilizing automated light systems. Ownership of these lighthouses has shifted to local governments, nonprofit organizations, and individuals. Some have been repurposed into residences, educational facilities, museums, or parks, contributing to local tourism.
According to the organization, climate change poses increasing challenges for these important coastal structures. The Gulf of Maine is experiencing significant warming at a rate three times higher than the global average, making these lighthouses exceptionally susceptible to rising sea levels and storm surges.
Recent coastal storms exacerbated by rising sea levels have caused damage to several lighthouses, such as the Portland Head Light in Cape Elizabeth and the Pemaquid Point Lighthouse in Bristol. The ongoing threats underscore the urgent need for preservation efforts to protect these landmarks.
The inclusion of Maine’s lighthouses in the World Monuments Watch list underscores the broader issue of climate change impacting coastal regions. As critical navigational aids and historical landmarks, these lighthouses not only hold cultural significance but also play a role in supporting the coastal economy through tourism. The effects of global warming, such as rising sea levels and increased severity of storms, pose a considerable risk to their integrity and continued operation.
The recent addition of Maine’s lighthouses to the World Monuments Watch list highlights the vulnerabilities they face due to climate change. It is imperative for stakeholders, including local governments and preservation organizations, to develop strategies that mitigate these risks and ensure the longevity of these historic structures. Addressing climate threats is crucial to safeguarding Maine’s maritime heritage.
