The holiday season in Historic Bethlehem officially begins with the return of Historic Bethlehem Museums & Sites’ beloved “Trees of Historic Bethlehem” exhibition and the new “Baked into Bethlehem” exhibition, which both opened Friday.

Tickets, which include entrance to both exhibitions, are available at historicbethlehem.org.

This year’s Trees of Historic Bethlehem exhibition is a curated showcase of the top trees and themes from the past 20 years, all beautifully staged across the Moravian Museum of Bethlehem, Kemerer Museum of Decorative Arts and Single Sisters’ House.

Presented in partnership with the Bethlehem Garden Club and community partners such as Hotel Bethlehem, Alloy5, Bethlehem Christmas Shoppe, Lucinda & Walt Dealtry, Tiller Private Wealth and WDIY Public Radio, the exhibition highlights the artistry, tradition and community spirit that have made Bethlehem’s holiday season famous around the world.

Also open is Baked into Bethlehem, the new exhibition tracing the evolution of baking as a cornerstone of community life, spirituality and creativity in Bethlehem for nearly three centuries.

The exhibition, which is on display at the Moravian Museum of Bethlehem and Kemerer Museum of Decorative Arts, highlights how baking has been woven into the city’s history and identity, from the beehive ovens of early Moravian Bethlehem to the beautiful wedding and birthday cakes of the beloved Groman’s bakery, which closed in the 1980s but still makes its Sugar Cookies for HBMS during the holiday season.

The opening of Trees of the Historic Bethlehem and Baked into Bethlehem exhibitions marks the start of HBMS’s exciting holiday offerings this year.
