FREDERICKSBURG, Va. (AP) — Former Gov. L. Douglas Wilder could be on the verge of losing the 38-acre property in Fredericksburg where he had planned to build a slavery museum.

According to the city treasurer’s office, the 38-acre property would be eligible for a tax sale Dec. 31, which would allow the city to collect unpaid real estate tax bills.

The Richmond Times-Dispatch reports that more than $142,570 is owed to the city in delinquent taxes for the property. City officials say it isn’t certain whether the city would proceed with a sale.

The land overlooking the Rappahannock River is vacant except for its small Spirit of Freedom Garden.

Earlier this year, Wilder formally notified the state that he was no longer attempting to raise money for the museum.
