Let's Build Something Together!

This competition returns for its second year! This local contest lets you show off your building skills with a chance to win one of our prizes. So trick out your bricks and max your knack for hacks with stacks of your own flock of blocks! Details are below.

Contest Information

Drop off Entries in Person on February 15

Entries can be dropped off at the Thunder Bay National Marine Sanctuary on 2/15 during regular business hours, from 8:00 am to 5:00 pm. Stop by the lobby desk when you drop off your build to pick up your registration card. They will show registered contestants where to place their build.

Announcement of Winners

Join us at 3:00 pm in the Theater for a formal awards ceremony! When we announce the winners for each division (1st, 2nd, and 3rd), their build will be showcased on the theater screen, and the winners will be called down to the front to accept their prize. We will also post the results on our website and social media, so check back here for updates after the competition!
