The Moon is one of 25 sites to be concerned about this year, according to a leading cultural heritage watchdog organization.

That organization is the World Monuments Fund, which today announced the 25 sites on its annual World Monuments Watch. The sites were selected from over 200 nominations that underwent two review cycles before selection by an independent panel of experts. The Moon stands apart from the rest as a cultural heritage site that is not on Earth.

“As we embark on a new era of space exploration, we must ensure that the traces of these extraordinary milestones in humanity’s history—the first moon landings—are preserved,” the release stated. “The inclusion of the Moon on the 2025 Watch advocates for international agreements and protections for lunar heritage sites and invites a broader public conversation on what this new Space Age might mean for the Moon’s cultural and natural landscape.”
