From Caln Township's website: 

Caln Township Parks and Recreation invites you to our annual Holiday Kids Party and Tree Lighting event!

Join us at 4pm at the Municipal Building for a kids party, featuring a special craft project – we'll be creating ornaments for the Township tree!

The Tree Lighting event will begin at 5pm on the Township grounds and will include carols by the Coatesville High School Meistersingers, refreshments from the Rotary Club of Thorndale-Downingtown and a visit from Santa!

The Hexagonal Schoolhouse will be open from 4pm-6pm and the Caln Historical Commission will be selling ornaments and pen and ink sketch prints of the schoolhouse as well as 2018 Old Caln Historical Society Susquecentennial calendars. These make terrific gifts!
