You are looking at University Hall in Lincoln Nebraska

Built in mid-1800s with a pop of 500! It didnt get its first 20 students until 1870

You can clearly see 4 stories of windows, with the last set 1/2 buried along with the original doors

New modern steps built to 2nd floor👇 ImageImage
They didnt even dig it yet. Simply built Lincoln around it.

All that remains now is the bottom section. You can see the original ground-level and the modern steps to the original 2nd floor.👇

~Why not add fireplaces and heating when it was available? ImageImage
