The 170-year-old Robe Obelisk was built as a navigation landmark to help guide ships into rocky Guichen Bay. It's in need of a repaint, but erosion of the limestone cliffs by pounding waves means it's now too dangerous to approach. The obelisk is predicted to collapse into the sea at some point in the next 30 years.

The Robe Obelisk was built in 1855 to help guide ships into the bay, and to store lifesaving equipment that was launched by rocket to stricken ships. Erosion of the cliffs it sands on will see it collapse into the sea within the next few decades, with all proposed engineering solutions to save it deemed too expensive.
