The city's main library, performing arts theatre, and exhibition gallery, in a 2006 building attached to the north end of Victoria Gardens. The 536-seat Lewis Family Playhouse hosts the city's theatre series, touring productions, and local orchestral concerts; the Celebration Hall is used for civic events and weddings.
The building itself is well-designed — light-filled, with a pleasant outdoor courtyard — and worth a brief look on a walk through Victoria Gardens. The library is open to visitors and has a good local-history collection on the Cucamonga Valley and Route 66.
