What do gorillas on rooftops, bat signals, and pleasantly fragrant alleyways have in common? They're all part of the Indy experience.

Recently, we were able to solve a few of the mysteries that have cropped up around the Circle City + they're just too good not to share.

"Have you seen this mammal?"

We're not sure how long this ape has been crowning Real Silk Lofts, but it's safe to say that the addition adds even more color to the already vibrant Chatham Arch neighborhood.

We took to Instagram to solve the mystery of the gorilla's origins + like always, our followers came to the rescue. They posed two likely theories:

"It's a resident that collects movie memorabilia and lots of cool stuff." — @zachwilks

"It is in fact part of decor from a Real Silk owner." — @beautymeetsgrace

And if this is true, we're hoping to be invited over soon.

"I live at Real Silk! There’s actually a large multi-story unit in that part of the building and that’s on their rooftop deck. They also have a bat signal and some other eccentric accessories. They can be seen from the Mill 9 rooftop deck." — @double0simo

Speaking of bat signals...

"I need a hero."

Been in Fountain Square at night lately? If so, you've probably noticed the bat signal donning the side of the Fountain Square Theatre Building. Though you won't find Commissioner Gordon waiting on the other end, you will find Hero House Comics, who are the real people behind the beacon.

"Did you smell that?"

Rose-colored glasses? More like rose-smelling alley. If you've smelled flowers while walking along the east end of Mass Ave., it's not just you. It's actually an art project by Arkansas-based Sean Derry and was installed nearly 13 years ago. "Chatham Passage" is an ornate steel grate with a built-in scent machine that pays homage to the historic + contemporary uses of the area.
