Located inside the former Hamilton Municipal Building, the new Heritage Hall and Robert McCloskey Museum officially opened on May 6, 2007 and is now open for tours.

Staffed hours are Friday, 9AM-5PM and Saturday 9AM-2PM; otherwise open by appointment only.  It takes approximately 45 minutes to view the history exhibit, the McCloskey Room and the Council Chambers. There are two separate video presentations on the life of Robert McCloskey.

A touch-screen kiosk shows different historic sites in Hamilton, the architecture of the Municipal Building and information on Robert McCloskey. Young McCloskey played a prominent role in both the exterior and interior design of this historic structure.
