COVINGTON, Ky. (AP) -- A group of Covington residents is hoping to turn a historic cemetery into a public park.

The Kentucky Enquirer reports the Linden Grove Cemetery was dedicated in 1843 and was the first local cemetery to be open to anyone regardless of race or religion. The 22-acre burial ground is listed on the National Register of Historic Places. It also is the largest green space in Covington's urban core.

Since 1998, Covington and Kenton County have each contributed $30,000 a year to the cemetery's upkeep.

After years of planning, supporters of Linden Grove Cemetery have a three-year master plan to raise the $3 million they need to make the cemetery self-sustaining.

Plans call for the space to become a public park with an arboretum and outdoor classroom.
