Step 5: Left side view
That's it - I just wanted to light up the steps - they are very crooked, and it is quite difficult to walk up them in the dark. I don't have a picture of the steps lit up in the dark - I forgot to take a picture after dark, but it is nice and bright.
Our farmhouse is ~143 years old, and I don't know how old the stairwell is - I have a picture of the house from 1911, which shows the steps. Anyway, the steps are at least 100 years old.
