Calling all Lego Lovers! We've got the club for you!

Visit the Library on the first Friday of each month to accept Lego building challenges.  When you've finished your masterpiece, it will be displayed in the Library.

This is an after-hours, family event -- everyone is welcome. Children under 9 must be accompanied by an adult. 

Registration is not required.  This is an after-hours event, so we ask that patrons use the West Lobby entrance only.

The Friends of the Longmont Library generously support library programs and services.
