Two Nights!

Friday, October 27th and Saturday, October 28th

Including People’s Choice Costume Contest!

On Friday, October 27th and Saturday, October 28th, the Harvard Square Business Association, in partnership with the City of Cambridge, welcomes you to an Illuminated Block Party from 7pm to 10pm.

From Mount Auburn to Brattle Street, JFK Street will be transformed into a pedestrian-friendly walkway where beer gardens, great food and live music welcome friends from near and far.

Have a beer and some bites at the legendary Whitneys Beer Garden. Sip cocktails, savor a delicious meal and watch the festivities from the Russell House Tavern’s charming patio overflowing with twinkle lights and flowers! Enjoy other restaurant options including Chutney’sEl Jefe’s TaqueriaLE’SLas PalmasLife AliveStarbucksSubwayTasty Burger and Union Square Donuts.

For the taking…glow sticks and Union Square donut holes while they last! On Friday Playa Bowls will be on site sampling mini Acai Bowls.

Costumes are encouraged!
Each night a winner will be chosen to receive a
$250 “Great Things Come in Harvard Square” gift basket!

This Illuminated Block Party will feature an interactive art installation by Pneuhaus, that invites visitors to power their own experience with bike-driven generators. As participants pedal, they collectively transform into a neon-colored grove of sculptural trees. These inflatable forms change color and contours continuously in time with the momentum of the bikers. Racing together, the field of plant-like pieces will inflate, deflate, illuminate, and darken.

JFK Street will radiate in an awe-inspiring and immersive installation by ILLUMINUS who will showcase a public art experience reflecting off the facades of our historic and iconic buildings.

This event is free and open to the public. All are welcome to join this family-friendly celebration.


This event is brought to you by the Harvard Square Business Association, in partnership with the Cambridge Public Space Lab, an initiative of the City of Cambridge Community Development Department, that explores new ways to bring life to everyday public spaces.
