Holy Cross in Collinsville was established in 1848 and saw the construction of 3 church buildings with the last being what is used for worship currently.

The first was a brick structure, the second made of wood frame. (1855)
Then in 1914 it was decided by the members that a bigger church was necessary, the cornerstone was laid and construction finished in 1915. It began with Pastor von Strohe and finished with pastor Klein.

This is how it looked in 1915. Over the years the front entrance has been altered to allow for fewer steps and for a more centered access. The cost was estimated to be $21,350 for the building and $30,000 for necessary furnishings. Member John Schroeppel donated half the bricks needed, Henry Eberhardt was the builder, the organ bought from the Wicks organ company ($2000), carpet paid for by the Ladies Aid, 3 good bells paid for by the Young Men's Society and the stained glass windows paid for by individual members.
As a side note, builder Henry Eberhardt was also the builder of the Miner's theater as well as the UMB 1st National Bank.
Interestingly, what was the front entrance shown in the picture above was bricked over in around 1948 or somewhat later. But if you look at the left side of the building, you can see the outline of the original doorway very clearly. How this can be mystifies me, but so it is.
Here is a better view of the old door shadow, Click to enlarge the pictures to see better.


And looking at the church from another angle, you can see other designs in the brickwork.

But you have to make the pictures bigger to see.
Oddly, another Lutheran church, Zion, was established in 1847 one year before Holy Cross and a new church around the same time (1920-ish) and was/is almost a twin of Holy Cross. It stands without much alteration from the original in Palmyra Missouri.

This church is still active but whoa, those outside stairs. As you can see, they did not change much, especially the entry. Their windows and pews and altar are in the same places and in the same numbers as Holy Cross's. The windows have the same stained glass borders but the images in the center are different. How amazing is this?

Interesting to go back in time and see what has continued.
