File talk:Paris in 9th century.jpg

I was wondering what the Notre-Dame on this map refers to, since the cathedral didn't start construction until 1163 CE, and the location on this map matches the present-day location of the cathedral. I couldn't find any reference to any of the earlier buildings on the site being referred to as "Notre-Dame". Is this an error, artistic license, or intended to indicate the future location of a major landmark? — Preceding unsigned comment added by CanuckMonkey (talk • contribs) 05:04, 18 February 2021 (UTC)
