There are some things a child shouldn’t see — such as the unexpected demolition of a historic tree outside their classroom window.

A heartbreaking video of the tree’s destruction was captured and shared Tuesday, during which a chorus of grade school students can be heard wailing in the background.

“Stop killing our tree,” many shouted as the hydraulic crushers snapped the massive tree limb by limb.

“A beautiful #birdofprey 🦅has been living in this #tree and the kids have loved watching it from their school. A true outpouring of emotion falling on deaf ears. Impossible not to feel emotional watching this. #saveenniskerry,” wrote @saveenniskerry, a Twitter account launched to advocate for responsible development in Enniskerry, Ireland.

The group has described themselves as “dedicated to preserving the heart, natural beauty and environment of the village.”

“To be clear, this tree, along with metres of hedgerow was destroyed to make way for development. It was not a farmer,” they added to the thread.

Footage was reportedly taken at the Powerscourt National School, Ireland’s oldest primary school which celebrated its bicentennial in 2018. The academy’s neighbor, the Powerscourt Estate, is home to one of the tallest trees — a Douglas fir — in the country, and seventh tallest in Europe, according to the Independent.

The tree’s axing was likely part of various plans approved last year to build nearly 500 new homes near the school, in a town that logged just 1,889 residents during their last reported census in 2016.

Save Enniskerry said it worries that recent commercial and residential development is changing the quaint community landscape.

“In recent months the quantity and scale of development applications that have been seen popping up has been surprising and not at all in keeping with the infrastructure and services available to the community,” it wrote in a recent post on Facebook.

“The tree was part of a hedgerow in quite an ecologically sensitive and diverse area,” Anita Tuesley, 58, a Save Enniskerry member and mother of four, told the Independent. “Both the tree and hedgerow are around 100 years old, there was a hawk in residence and there are bat roosts in the vicinity.”

However, there is no indication that developers broke building regulation by taking down the tree.
