Celebrate Halloween with several spirited events Friday afternoon at the Fairfield Public Library.

In conjunction with the 150th anniversary of the publication of Lewis Carroll’s “Alice’s Adventures in Wonderland,” the activities will have a Wonderland theme, but eveyone is encouraged to wear costumes of their choice to the library, corner of Old Post and Post roads. The free Halloween festivities are drop-in events, registration is not required.

The activities will include:

“Not-So-Scary Halloween Story Time,” 2 p.m.: Designed for young children up to 5 years old, the program will feature Halloween rhymes and stories, along with a trick-or-treat costume parade around Wonderland! Costumes are encouraged, for both children and adults!

“Mad Hatter’s Tea & Halloween Party,” 4 p.m.: For kindergartners up to fifth grade, the program will include flamingo croquet, the Mad-Hatter’s un-birthday, the Red Queen’s costume contest and other activities.

At the same time, Trick or Treat on Safety Street will be going on downtown, so it promises to be a spirited afternoon.
