MICHIGAN CITY, Ind. (AP) -- A historic lighthouse that has stood sentry over Lake Michigan could soon get protection of its own.

Michigan City officials are considering installing a surveillance camera to protect the 1904 lighthouse from vandals who’ve marked it with graffiti.

Harbormaster Tim Frame says crews painted over a recent wave of graffiti, only to have fresh markings show up on the 50-foot-tall lighthouse the same night.

The lighthouse is featured prominently in tourism marketing materials.

Officials say they’ll study the cost of a surveillance camera and other ideas for stopping the vandalism before deciding how best to protect the structure.
