About Us

About The Maritime Explorium at Port Jeff Harbor:

The Maritime Explorium encourages visitors to explore and play together in our hands-on interactive maker space rich with nautically themed science based exhibits and activities. While our focus is children ages 2-12 and their caregivers, we welcome visitors of all ages.

The Maritime Explorium was launched in 2004 as “The Children’s Maritime Museum at Port Jefferson” (CMM) by a group of local residents seeking a family-friendly educational experience.

In May of 2005, CMM received designation as a 501(c)3 not-for-profit and is chartered with the New York State Department of Education. Through an agreement with the Village of Port Jefferson the museum opened in temporary quarters in the Port Jefferson Community Center while our permanent facility, the historic Chandlery Building, was under renovation.

In March of 2011 renovations were complete on the the Chandlery and the museum moved in and reopened as the “Maritime Explorium at Port Jeff Harbor.” Since that time we have grown into a thriving regional family museum where learning is at the heart of having a good time!

We continue to grow and add new programming and opportunities for the public, schools and private groups to engage in engaging hands-on activities.

Maritime Explorium Mission:

Families exploring the fun and interactive hands-on exhibits at the Maritime Explorium at Port Jeff Harbor will enjoy the excitement of scientific discovery, develop a broadened cultural awareness and experience a sense of artistry while learning about Long Island’s rich and varied maritime heritage.
