Those driving by the two churches on the opposite sides of Sixth and Center streets will probably notice that each is undergoing separate sprucing-up projects — one involving intensive construction and the other aimed at saving a piece of history.

St. Paul Lutheran Church is replacing its roof, a project that is costing the church about $70,000, most of which is being raised through a capital campaign.

Crews moved in last week and are hoping to complete the project in the next few weeks, said the Rev. Mike Poole.

Poole said the replacement is a necessity because of leaking throughout the church building. He said simple patching of the roof was not an option due to the extent of the problem.

The church’s educational wing in the rear of the church was constructed in the mid-1990s, he said, and does not need repairs.

Across the corner at St. Lawrence O’Toole Church, a 16-foot circular stained glass window depicting St. Patrick has been removed and has been shipped to Iowa for repairs.

The window has been in place since the church was built in 1892 and has, naturally, begun to show its age, said Father Anthony Batt.

Batt said the window has been removed piece by piece and the glass is being re-leaded. The wooden frame of the window, that had began deteriorating, is being replaced.

The window is expected to arrive at the church in sections the first week of May, when it will be pieced together at the site.

Money for the repairing of the window is being paid for in part by donations from parishioners. The Ancient Order of Hibernians, an Irish-American Catholic Fraternal Organization founded in New York in 1836, has given the church a donation for the project, as well.
