[citation needed] The 50,000 sq ft (4,600 m2) museum received over a quarter of a million visits from children and their families every year.

In March 2021, the museum announced it would permanently close at the end of June, due to the financial loss brought on by the COVID-19 pandemic.

The Lair Hill Museum contained a pet library (from which children could check-out animals) as well as a variety of interactive and informative exhibits.

The Lair Hill museum hosted regular arts and crafts workshops as well as sports games and other activities.

Myriad exhibits, including Water Works, Play-it-Again Theater, Building Bridgetown, Groundworks, Outdoor Adventure, and the Baby's Garden, along with the museum's art studios, The Clay Studio, The Wonder Corner and The Garage encouraged playful inquiry, cultivated creative expression and helped children learn how to learn.
