What is the scene depicted in the second “Waterdeep Digital Background” art?

In the Free Remote D&D Resources archive that Wizards of the Coast is providing, for April 30, 2020 there is a “Waterdeep Digital Backgrounds” zip file that includes artwork that one might be able to use as a background while videoconferencing. The second file (named “DnD_Video_bg-WDDH2”) looks to be a scene outside of Waterdeep proper, with people along a path, a building (maybe some kind of temple), and the wall of Waterdeep in the background. I’m presuming putting a smaller version here counts as fair use:

Waterdeep scene 2

What is that building, and more generally where is this scene set? Is it part of the Waterdeep: Dragon Heist book or storyline? (I don’t remember seeing it in there, though probably I just missed it, but the filename saying “WDDH” makes me think it’s related.)
