Kenner Mayor Mike Yenni turned on the lights to the Heritage Park Christmas tree Friday night in Rivertown.

Santa was on hand, and the Loyola Brass Quintet performed holiday musical favorites.

The display is open through Dec. 21. On Saturdays, the Kenner Planetarium and MegaDome Cinema, 2020 Fourth St., will present a special holiday-themed planetarium show, “Season of Light,” starting at 7 p.m., and a musical laser light show, “Laser Holidays,” at 8 p.m.
