Dark Skies Cornwall

Under a pitch black starry sky in West Penwith, when sitting by some of the ancient monuments, we are looking at the very sky that 2000 years or more ago our ancestors were looking at. We must protect that sky for future generations….

The International Dark Sky Places Conservation Programme recognises and promotes the excellent stewardship of the night sky.

About

Cornwall National Landscape has two DarkSky International Dark Sky Places that cover the whole of Section 07, West Penwith and Section12, Bodmin Moor.

Aim

Preserve and enhance the dark night skies above West Penwith and Bodmin Moor for pleasure, leisure and to support the wellbeing of residents, visitors and wildlife.

About DarkSky International

About DarkSky International

DarkSky International, formerly known as the International Dark-Sky Association (IDA), was founded in 2001 to encourage communities, parks and protected areas around the world to preserve and protect dark sites through responsible lighting policies and public education. DarkSky International offers five types of designation from communities which are legally organised cities and towns that adopt quality outdoor lighting ordinances to Sanctuaries which are the most remote (and often darkest) places in the world. Their conservation state is most fragile.

Cornwall has successfully designated two International Dark Sky Places, which are Sections of Cornwall National Landscape. The parks are publicly or privately owned spaces protected for natural conservation that implement good outdoor lighting and provide dark sky programmes for visitors.

Project Detail

Bodmin Moor International Dark Sky Landscape

In July 2017 Bodmin Moor, Section 12 of Cornwall National Landscape, was designated an International Dark Sky Landscape, confirming its status as one of Cornwall’s star attractions and making it the first International Dark Sky Place in a National Landscape.

Following a bid by Cornwall Council and Caradon Observatory, Dark Sky International (formerly International Dark-Sky Association) awarded the prestigious designation in recognition of the exceptional quality of the night sky over Bodmin Moor, commitments to avoid light pollution and the provision of educational outreach. Bodmin Moor International Dark Sky designation covers the portion of the Moor within Section 12 of Cornwall National Landscape PLUS a two-mile buffer zone around it.

Star-gazing opportunities on Bodmin Moor are at their best in the darker spring, autumn and winter months. The designation brings health benefits for both people and wildlife in the moor’s living landscape by helping to keep artificial light at a very low level. Within the designation area residents and businesses are encouraged to protect the night sky from light pollution by managing their lighting better.

“….Bodmin Moor’s status as an International Dark Sky Landscape is especially noteworthy. Its position within the Cornwall National Landscape clearly establishes that the conservation of dark night skies is wholly compatible with the notion of protected landscapes where people routinely live and work.”

Dark Sky International ex-Executive Director J. Scott Feierabend

Benefits

Our Primary Purpose is to conserve and enhance Natural Beauty.

Our priority is to lead and support projects which deliver under these four key categories.

benefit to people

People

Humans evolved to the rhythms of the natural light-dark cycle of day and night. We need darkness to thrive.

benefit to place

Place

Experiencing the night sky provides perspective, inspiration, and leads us to reflect on our place in the universe. It is our common and universal heritage.

benefit to nature

Nature

Plants and animals depend on Earth’s daily cycle of light and dark rhythm to govern life-sustaining behaviors such as reproduction, nourishment, sleep and protection from predators.

benefit to climate

Climate

DarkSky International estimates that least 30% of all outdoor lighting (USA) alone is wasted, mostly by lights that aren’t shielded. This equals $3.3 billion and 21 million tons of CO2 per year! To offset we’d have to plant 875 million trees annually

West Penwith is only the seventh area of the UK and the second in Cornwall (after Bodmin Moor) to become an International Dark Sky Park (IDSP).

The West Penwith IDSP covers the westerly section of Cornwall National Landscape; it stretches around the coastline from the outskirts of St Ives, through to St Just, Sennen and around Land’s End to Mousehole. Inland it takes in Trethewey, Sancreed and New Mill. The designation recognises this area as being naturally dark at night, with minimal traces of light pollution, making West Penwith one of the best places in the world to view the beauty of the night sky.

Cornwall Council supported a partnership among residents, businesses and councillors to achieve the accolade. A Steering Group comprised of local Councillors, Cornwall Council officers, PK Porthcurno, Land’s End Accommodation Providers, The National Trust, Cornwall National Landscape, Mayes Creative, Penwith Landscape Partnership and other passionate locals led the efforts for this IDSP nomination.

Celebrate Cornwall’s stunning night sky this International Dark Sky Week 21-28 April

International Dark Sky Week is a global event dedicated to appreciating the beauty of the night sky and raising awareness about the importance of dark skies, inviting everyone to explore the wonders of the night and take action to protect our nocturnal environment.

Look up into the night sky. How many stars can you see? Light pollution continues to grow at an alarming rate, doubling globally every eight years, taking away our view of the stars while harming human health and critical wildlife habitat, according to scientific studies. From enhancing wildlife biodiversity to preserving cultural heritage, dark skies are essential for a healthy planet.

Let’s come together this International Dark Sky week, to celebrate our astronomical heritage, enjoy the night and ensure that future generations can also enjoy the beauty of a star-filled sky.

Are you light pollution aware?

As lighting options become more inexpensive and brighter, we are illuminating the night more and more, creating glare and skyglow that destroys critical nocturnal wildlife habitats, harms human health, and diminishes our view of the stars.

Today, 80% of the world's population lives beneath light-polluted skies. Every eight years, light pollution around the world doubles! Did you know, smart and simple lighting practices around your own home and community can make a difference? DarkSky International has five easy steps to help ensure your lights protect the night!

Cornish connections to the cosmos

Cornwall has a rich history of connection with the night sky

Many of our megalithic sites are linked to the solar or lunar cycles. Some have links to the stellar cycle. Cornwall was also the birthplace of pioneers such as John Couch Adams (pictured), one of the two people who independently predicted the existence and position of Neptune using mathematical calculation and Malachy Hitchins, the vicar of St Hilary, whose work on the Nautical Almanac enabled sailors to navigate using tables of the position of the Moon and planets.

Archaeoastronomy

“Meet Archaeoastronomer Carolyn Kennett to discover more about Cornwall's rich history of ancient sites with astronomical importance”

What got you interested in archaeoastronomy?
I’ve always loved history, and as an astronomer, discovering archaeoastronomy felt like finding my perfect niche. I’m fascinated by how ancient cultures connected with the sky, and I love sharing that wonder—there’s something magical about explaining how a sunset aligns at a historic site and seeing people’s amazement.

How and when did you get started?
My background is quite varied, but I became more serious about archaeoastronomy while studying for my astronomy degree. That’s when I realized how much I enjoyed exploring the connections between ancient structures and celestial events.

Do you use any special equipment or have any special training?
Yes to both! Surveying equipment and a solid understanding of astronomical software are incredibly useful. That said, you don’t need specialist tools to get started—anyone can explore archaeoastronomy with curiosity and a keen eye.

Where are the best places in Cornwall National Landscape for archaeoastronomy?
Cornwall is full of amazing sites! Chun Quoit and Tregeseal Stone Circle are incredible spots to watch the winter solstice sunset.

What are your top 3 tips for beginners in archaeoastronomy?
1. Learn the Basics – Understand key celestial events like solstices and equinoxes and how ancient cultures observed them.
2. Explore Ancient Sites – Visit places like Stonehenge or Chichén Itzá to see how people aligned structures with the sky.
3. Use Technology & Get Outside – Apps like Stellarium help visualize ancient skies, but nothing beats experiencing the stars and historic sites in person!

Cornwall has a rich astronomical heritage. Megalithic sites with links to astronomy are found throughout Cornwall, but primarily on; Bodmin Moor, West Penwith, the Lizard and also the nearby Isles of Scilly. Many of the sites within the area are linked to the solar and lunar cycles. Some have links to the stellar cycle.
