A century-old landmark of Long Island needs some repairs.

Part of the Fire Island Lighthouse Tower is shut down because of damage that may have been caused by the weather.

The National Park Service says an exterior panel on the northeast side of the lighthouse “separated from the structure.”

It called the damage “more cosmetic than it is structural” and said the closure was out of an abundance of caution.

“Half the terrace will be closed on the north side and boardwalks leading to the north side of the lighthouse will be closed until further notice...the lighthouse structure will remain temporarily closed until further notice."

Tours of the lighthouse have been suspended, but the Lens Building, museum and gift shop will remain open.
