JEFFERSON CITY (AP) – It won’t be long before Missouri residents will once again have the chance to tour a former state prison.

The Jefferson City News-Tribune reports that tours in limited areas of the Missouri State Penitentiary are scheduled to resume April 21. Public tours were stopped last fall after high levels of mold were discovered.

The Jefferson City Convention and Visitors Bureau announced that full walkthroughs of the facility would begin July 1.

Last year, the city agreed to split with the state the estimated $2 million in repair costs and mold remediation at the former prison.

The Missouri State Penitentiary opened in 1836 and was the oldest continually operating prison west of the Mississippi River when it shut down in 2004.
