I looked all over for a date and got everything from “early 1800s” to “late 1800s” but nothing exact, so I had to make an educated guess. The first cameras practical enough to take such a photo were developed around 1840 and the excavations began in 1867.
Fantastic find!
Why didn’t you just look at the metadata? It appears this photo was taken in the year “© All Rights Reserved”
I felt that copyrighting it in the year nothing might have been a typo.
Also, there’s absolutely no question that it’s public domain.
A not very trustworthy looking hungarian website says 1890
Maybe, between two excavations, the wind has partly filled up the cavity of the previous excavation with sand and thus, the progress wasn’t continuous.
This is supposedly from 1867 - 1878:
