Welcome to the Cross-Channel Geopark

Step into a world where geology and culture meet across borders, linking the stunning chalk landscapes of southern England and northern France. The Cross-Channel Geopark offers a unique opportunity to explore a landscape shaped over millions of years and shared by two nations. From ancient chalk cliffs to vibrant local communities, this is a place where natural beauty, history, and human connection come together in harmony.

What is the Cross-Channel Geopark?

The Cross-Channel Geopark is a cross-border partnership between the Kent Downs National Landscape and the Parc naturel régional des Caps et Marais d’opale that celebrates the geological, cultural, and historical ties between Kent in the UK and Pas-de-Calais in France. Together, these regions form a single, remarkable landscape connected by a common geological story and shared heritage. By preserving and promoting this unique area, the Geopark invites you to explore the history of the land beneath your feet while fostering sustainable tourism and cultural exchange.

We are currently applying for UNESCO Global Geopark status—a prestigious recognition that celebrates areas of international geological significance. UNESCO designation would highlight the importance of our geological heritage and ensure that it is protected for future generations, while bringing worldwide attention to this remarkable region.

Our Geological Story

The Cross-Channel Geopark’s geological foundation is the extensive chalk that forms its backbone, stretching from the cliffs of Kent to the shores of northern France. This chalk, created during the Late Cretaceous period over 70 million years ago, is a direct link between our two regions. During this time, the area was submerged beneath a warm, shallow sea, where billions of tiny organisms known as coccolithophores settled on the ocean floor, creating the vast layers of white chalk we see today.

These chalk formations are among the most iconic natural features of both regions, from the famous White Cliffs of Dover in Kent to the imposing Cap Blanc-Nez in France. Together, they create a shared geological identity—one that speaks to the deep connection between the land and the sea, and between two nations. Beneath the waves, these chalk formations continue to unite the regions, forming an unbroken geological link across the Channel.

The Formation of the English Channel

One of the most dramatic events in the geological history of the Cross-Channel Geopark occurred around 450,000 years ago, during the Anglian Ice Age. A massive glacial lake formed behind an ice sheet, eventually breaking through the chalk ridge that once connected Britain to mainland Europe. This catastrophic flood carved out the English Channel, separating the landmasses and creating the waterway we know today. The submerged chalk ridge beneath the Channel is a reminder of this ancient land bridge, offering a unique geological link between the two coasts.

Explore the Geopark’s Hidden Stories

The Cross-Channel Geopark is home to numerous Geosites, key locations that showcase the rich geological, historical, and cultural significance of the landscape. These Geosites offer a window into the Earth’s history and the dynamic processes that have shaped this region. From fossil-rich chalk cliffs to hidden valleys and ancient caves, the Geosites are the stars of the Geopark, each telling a unique part of the geological story and how these geological processes have shaped both the landscape and the lives of those who live within it.

What is a UNESCO Global Geopark?

UNESCO Global Geoparks are areas of international geological significance that promote the sustainable use of natural resources, conservation, education, and eco-tourism. At present, there are 177 UNESCO Global Geoparks in 46 countries and the list is growing. Geoparks are not just about protecting geology; they are about celebrating the connection between people, culture, and the landscape. In the Cross-Channel Geopark, we aim to use our shared geological story to bring communities together, foster cross-border collaboration, and inspire a deeper understanding of our natural heritage.

Our Geopark’s UNESCO application is not just about recognition; it’s about creating a lasting legacy. By achieving UNESCO status, we will ensure that the geological and cultural heritage of this region is protected and promoted, allowing future generations to learn from and enjoy the land that unites us.

The 'Big Bang'

13.8 billion years ago

Earth formed

4.6 billion years ago

 

540 million years ago

The Cambrian explosion of life: animals evolved and diversified as never before on Earth.

Devonian

419 million years ago

390 million years ago the oldest rocks you can see in the Geopark date back to the Middle Devonian. They are still quarried today in the Marquise basin in France.

Carboniferous

359 million years ago

Around 325 million years ago the Geopark was near the equator. The swamp forests from that period are preserved as coal, which was formerly mined in the Marquise basin in France as well as in East Kent and the Nord-Pas-de-Calais.

Permian

299 million years ago

Triassic

252 million years ago

210 million years ago the Geopark was in the centre of the Pangaea supercontinent, and dinosaurs roamed the land!

Jurassic

201 million years ago

150 million years ago the Geopark was submerged under the sea, the sands, clays, limestones, and sandstones that compose the Boulonnais region in France were deposited.

Cretaceous

145 million years ago

Over about 40 million years from 100-60 million years ago, Chalk formed at the bottom of a warm, shallow sea where the Geopark is located today. This was the first step towards the formation of our distinctive chalk landscape, which defines much of the Geopark.

Palaeogene

66 million years ago

Tectonic activity around 40 million years ago uplifted the territory of the Geopark by dozens of metres, creating an extensive chalk landscape that connected France and Great Britain.

Neogene

23 million years ago

Quarternary

2.6 million years ago

450,000 years ago, a megaflood destroyed the chalk ridge connecting Calais and Dover, creating the iconic white cliffs of the Geopark we see today
