VINCENNES, Ind. (WTWO/WAWV) – The National Park Service is investigating widespread theft of panel covers for historic bronze lampposts within the George Rogers Clark National Historical Park.

The panels from these lampposts are made of a mix of bronze and copper. The historic lampposts are about 90 years old.

Chief of Interpretation Joe Herron said that 22 lampposts had panels stolen and another four had screws loosened in preparation for removal. Each panel weighs about nine pounds.

Herron said that the park is currently in the process of adding more security and replacing the panels, but much of the history from lampposts is gone.

“In many ways they’re irreplaceable because they are original,” Herron said.

Anyone with any information about the thefts is asked to contact the park at (812)-882-1776.
