Black Cat Alley
Hidden behind the Oriental Theatre between Prospect and Farwell Avenues, this once-desolate alleyway was transformed into a dense, open-air gallery of street art and murals. The walls feature rotating large-scale works including surrealist creatures, 3D optical illusions, and vibrant pop art.
The story
You could easily walk past the narrow corridor between Prospect and Farwell Avenues without ever glancing down it. Tucked directly behind the historic Oriental Theatre, this passage spent decades as just another desolate service lane for dumpsters and deliveries. That changed when the East Side Business Improvement District helped claim the private alleyway, turning forgotten brick and concrete into a dense, open-air gallery.
The result is Black Cat Alley, a secluded urban canyon where artists paint directly onto the building infrastructure. Instead of velvet ropes, you're standing on pavement surrounded by rotating large-scale works ranging from surrealist beasts and 3D optical illusions to sharp pop-art pieces. If you pay close attention as you walk the walls, you'll start noticing small, hidden cat silhouettes subtly integrated into the mural details.
What it's like
Slip into the alleyway off Ivanhoe Place or North Avenue, ideally with a coffee or boba tea in hand. Because it is an open-air alley, you can wander through at your own pace; visiting in broad daylight gives you the best angle on the fine paint textures and hidden silhouettes. The brick passage is narrow, so it can feel intimate when small groups gather, but the vibe remains casual and accessible. Keep an eye out for occasional scheduled evening events like Black Cat Alley After Dark when the alley fills with music and late-night art crowds.
The move: Grab a boba tea or coffee around the corner on E North Ave and stroll through the narrow brick alleyway to spot the hidden cat silhouettes tucked into the murals.
