Long-Island-Explorium2

The Long Island Explorium is housed in the beautiful historic Chandlery Building in Port Jefferson village.  The building was built in the 1890’s and served as the chandlery, a store that sold nautical gear, candles, rope, sail repair kits and all of the other equipment a ship would need for a long voyage.

Visitors to the Explorium will enjoy fun and interactive hands-on exhibits all aimed at fostering the understanding and love of STEM.
