Elisabeth Rowark, Chair of the Northumberland Dark Skies Working Group and Director of the Kielder Water & Forest Park Development Trust, said:
"We have worked so hard together to reach this tremendous day for everyone committed to securing protection for England's largest area of starry skies. We have a wonderful story to tell in terms of our public astronomy outreach and the success of the Kielder Observatory. But this designation as Europe's largest Dark Sky Park will be a springboard allowing us to do even more. We do not want to turn off the lights, but rather encourage better lighting using the latest technology. This is the start of a new chapter for Northumberland where quite literally the sky is the limit."
