Here's what it looked like in c1900. Once again, we have a lost spire. One very unusual feature is the presence of those two round windows, and particularly the way they're arranged. A single rose window, in the middle, was common, but two, side by side, is rather odd. The transom over the entrance looks like it might have been stained glass. Very interesting building.
Now, as I've said, Holy Angels is considered the oldest parish church in the diocese, but there's a problem.
This is what it looks like today. Very nice building, but not the same. Everyone I asked agreed that the original church is somewhere in there, but no one could tell me when and how the change was made, until now.
A few days ago, Kevin Hammer drew my attention to an excellent blog called Sandusky History, written by the staff of the Sandusky Library Archives Research Center. I left a comment asking for information and they responded quickly.
Fr. Thomas P. Lamb, pastor from 1893 to 1903, carried out an expansion project which was finished by 1902. An 35-foot addition was built in front of the church. The original tower was removed and replaced with one at the side. The 1843 church is still there, but looks completely different from the front. Holy Angels is the oldest extant parish church in the diocese, with the caveat that St. Patrick's in Providence, built I believe in 1848, is the oldest to survive in its original condition. That nakes two to be recognized.
