I solved this too! This was an awesome challenge, I loved it! multi-part challenges are my favorites to solve (I replied with my writeup on the solution post instead of this one on accident haha oops)

I'm so excited to say I managed to solve this one! This was the most fun I've had in an OSINT challenge yet!

but was unable to get a search to work. Admittedly, I'm on a bit of a time crunch and didn't try too hard to figure it out 😅. I'm really glad that I decided to check my work before continuing by seeing what other people found, because I would have spent a *long* time in Argentina looking.

Well, I tried earthkit, which sent me looking around Milan and Rome, and I tried the Geoguessr GPT, which had me looking around La Plata, Argentina. Apparently, the 0221 area code corresponds to La Plata, and it got so fixated on that, it wouldn't search any other places. I also tried findthatspot

I will say, a hilarious number of stock photos use this pavement without saying where it is

oh man, it gets so much better. If you do a reverse search *only* on the floor dots, a Reddit user complains about a vent mis-alignment. It just so happens that this misalignment is at the same location! Whether I could've gotten the location from that though...

(2/3) a ufo-shaped thing on the top. To the left is a large rectangle, probably another sign. In Google street view, when positioned at the same angle as the photo, there is a single signpost that matches the shadow, and there's another sign to its left that matches the rectangle!

(1/3) A quick reverse image search showed that this is the Musée Futurium in Berlin, Germany. After a minute or two of repositioning the google maps street view, I found the correct angle. There's a sign that matches the shadow on the ground. The shadow depicts four big signs, two small signs, and

This was a bad continuation of thought. I found the park, then searched through the images of the park on Google maps until I saw the correct play structure

Wild, that's amazing! It never occurred to me to just count the seats and Google!

I think this one's got to be it. The wheelchair access locations match up, and the pattern of the seat chart outline/silhouette matches perfectly. What did you do to find this location?

I suppose I should include where this was taken from

... who had posted almost exactly the same picture! I'll figure out the time later. I've got some ideas on things to try

Found it! Mauerpark, Berlin. A reverse image search on the photo yielded a linkedIn post. The linkedIn url didn't lead to the correct post, but I scrolled down the user's posts until I found the picture, and they had labeled the location! Then, scrolling through the images on Google ...

The last thing I noticed so far is the arrows near the front, most likely indicating doors. I wonder if the other wheelchair markers are also doors or maybe are just indicating that the aisles on the sides don't have stairs?

I've looked through photos of concert halls in Germany, and the majority of the ones I've seen don't actually have curves seating like that. Instead, it's usually two sections of straight rows with an aisle down the middle. This might be unique enough to narrow down locations

Assuming that the yellow seats are the available ones, it's interesting that the front ones are the last to go. Might imply that it's somewhat uncomfortable to be that close. Maybe too loud, maybe you have to strain your neck

The venue could have balcony seating though, which would possibly double the size of the venue depending on configuration.
