Highlights of the Isle of Portland Walk

The Isle of Portland Walk

So now we covered the basics. let’s get to the walk!

Portland Heights

Our adventure begins at the New Ground carpark, nestled atop Portland Heights Beacon Hill. This vantage point offers unparalleled views over Chesil Beach, an impressive 18-mile-long pebble bank that forges a natural bridge between the Isle of Portland and Weymouth. To the right, the harbour unfolds, its history deeply intertwined with the maritime legacy of the area. Constructed between 1848 and 1905, the harbour once served as a pivotal Royal Navy base during both World Wars. It then transitioned into a training ground for the Royal Navy and NATO and then into a civilian port in 1995.

The harbour’s notable role during the 2012 Olympic Games, particularly for the sailing events, is commemorated by a sculpture of the Olympic Rings, a symbol of that unforgettable summer when the world’s gaze was fixed upon Portland Harbour.

Castletown

As we venture towards Castletown, one of the island’s eight settlements, the journey takes us down New Ground towards the northeast.

Here, we share the road with passing vehicles. En route, the silhouette of HMP The Verne. one of the island’s two prisons, emerges on the cliffside. The road leads us past the prison’s gates, flanked by deep moats.

At the end of the road, turn right onto Glacis. I must admit that walking alongside the prison fence is not the prettiest part of this walk. But you will be rewarded in the end as you get to the Fancy’s Farm. This family-friendly destination offers glimpses of diverse animals, from traditional farm inhabitants to exotic alpacas and wallabies, enriching our walk with unexpected encounters.

Grove

As we progress further into our exploration, we arrive at our second significant stop: the Grove. This area of the island is marked by two notable landmarks. The first is the East Weare Battery, a historical gun battery constructed in the 1860s as a defensive measure to safeguard the harbour from potential invasions. By 1956, it had been decommissioned, and today, parts of the remaining structure are recognized as ancient monuments.

The second noteworthy structure is the HR Prison Portland, specifically designated as a Youth Offender Institution for young males aged between 18 to 21 years. Originally inaugurated in 1848 to house male convicts, it significantly contributed manpower to the island’s quarries. By 1921, it had evolved into a youth detention centre and then a Youth Offender Institution (YOI) in 1988. Beyond its primary role, the institution doubles as a rehabilitation centre, offering valuable work experience to the offenders at the Verne Prison cafe, a site we encountered earlier in our walk.

Having explored the rich history of the island’s correctional facilities, we find ourselves at a juncture. Here, at the road’s end, we take a left turn onto a footpath that leads us down the cliff. As we meander along this path, the Isle of Portland reveals itself in a new light. With the expansive sea to our left and the towering chalk cliffs of Grove Cliff behind us, we are enveloped in natural beauty. The view of prison walls and fences fades into memory, replaced by the wild vegetation cascading towards the sea.

Church Ope Cove

Continue your journey down the slopes of Grove Cliff, and you will find yourself confronted with the beauty of a wall in ruins. This remnant is a part of Rufus Castle, the most ancient castle on the island. Constructed under the auspices of King William II, known colloquially as King Rufus, the castle bears his name and legacy.

Over the span of centuries, Rufus Castle has seen a multitude of proprietors, each leaving their mark through various modifications and restorations. The edifice that stands before you, weathered yet resilient, dates back to the fifteenth century. Perched atop a rugged rock, it commands a breathtaking view over the Shambles sandbank—a notoriously treacherous navigation zone that has claimed many a ship. Since 1951, this architectural marvel has been recognized as a Grade I-listed building.

Descend to the beach below, an inviting haven perfect for a break. Here, allow yourself to be soothed by the rhythmic cadence of the waves crashing ashore. Surrounded by the vast expanse of the sea and the quaint charm of colourful cabins, this spot offers an idyllic backdrop for relaxation and contemplation.

However, like all journeys, this moment of peace eventually must come to an end. The path beckons you to leave the beach and rejoin the coastal trail that lies ahead. Fear not the upcoming scramble—it promises to be a manageable ascent, offering another layer of excitement to your exploration.

Bill Lighthouse

As we continue our journey, the path reveals the architectural remnants of a bygone era, where quarried stones were once hoisted onto boats by towering cranes. On the horizon, the iconic Portland Bill Lighthouse, adorned in its striking red and white stripes, marks the southernmost tip of the island, serving as a guiding beacon to mariners.

Historically, the island was safeguarded by two lighthouses: the Old Lower and the Old Higher Lighthouse, both instrumental in navigating ships away from the perilous Shambles sandbank. However, their watchful eyes were dimmed with the commissioning of the current Portland Bill Lighthouse in 1906. The latter continues to operate to this day, albeit remotely since 1996. A visit to this lighthouse invites guests to ascend the 153 steps to its summit, a climb that rewards breathtaking views.

Undoubtedly, the activities of the day are bound to stir up an appetite, making the proximity of the Lobster Pot to the Portland Bill Lighthouse a welcomed convenience. This charming eatery provides a diverse menu of sandwiches, hearty meals, and a selection of beverages, ensuring that there’s something to satisfy every palate.

Replenished, we retrace our steps towards the coastal path’s cliff edge, where another historical marker awaits— the Trinity House Obelisk. Erected in 1844 from the locally sourced Portland Stone, this obelisk is a testament to maritime safety, warning passing ships of the nearby shallow reef.

Blacknor Fort

As you continue your journey along the coastal path, the silhouette of Blacknor Fort gradually comes into view. Constructed between 1900 and 1902, it was initially erected as a formidable bulwark against potential enemy incursions, playing a crucial role in the coastal defences throughout both World Wars.

One of the most poignant chapters in the fort’s history unfolded on the night of 27 April 1944, an event known as the Slapton Sands Massacre. During this dark hour, U.S. soldiers, engaged in preparatory exercises, found themselves under fierce attack by German naval forces. Tragically, Blacknor Fort stood as a helpless witness, with orders strictly forbidding engagement to avoid the risk of inflicting harm on allied troops. The devastating outcome saw the loss of over 600 American lives, many of whom were dragged down into the depths, burdened by their own gear.

By 1956, the fort was officially decommissioned and has since transitioned into private ownership. Today, as the coastal path weaves beneath the cliffs, the Blacknor Fort’s structure becomes challenging to discern, offering little indication that one is passing directly beneath this historic site. Emerging on the other side, visitors are met by a distinctive half-shell formation on the ground. It marks the former site of a powder gun emplacement. This subtle landmark serves as a reminder that Blacknor Fort lies just a stone’s throw away,

Tout Quarry Reserve

We continue on the coastal path until we meet an intriguing stone arch. This is our sign to transition from the rugged cliff edge to the charm of the mainland. This archway acts as a gateway, directing you towards the enchanting realm of the Tout Quarry Reserve & Sculpture Park.

Historically, this quarry played a pivotal role in the eighteenth and nineteenth centuries, serving as a bustling site for commercial extraction. However, its industrial heartbeat came to a halt in 1982, only to be reborn with a new purpose the following year as a sculpture park. This transformation was spearheaded by the creative endeavours of local artists, whose inaugural sculptures laid the foundation for what would become a dynamic canvas of artistic expression. While some creations have stood the test of time, others were more transient, leaving behind tales of ephemeral beauty.

Each year, the quarry welcomes a fresh wave of artists, infusing the park with an ever-evolving vibrancy. Beyond the art, the quarry cradles an ecosystem of its own, hosting diverse colonies of butterflies and nurturing rare flora like the rock stonecrop.

Entrance to the Tout Quarry Reserve & Sculpture Park is free, offering all who visit the Isle of Portland an irresistible opportunity to immerse themselves in the fusion of art, history, and nature that defines this special place.

Sunset on the Beach

Following an enriching visit to the Tout Quarry, the journey leads us back to the coastal path, initiating a gentle descent towards the picturesque Chesil Beach. En route, a poignant statue captures our attention. Known as The Spirit of Portland, this artwork, conceived by Joanna Szuwalska and unveiled in 2000, embodies the island’s heritage through the figures of a fisherman and a quarryman – pillars of the local economy and community.

As the path unwinds down the hillside, leading to the promenade that hugs the beach, the ambience shifts, drawing us closer to the tranquil rhythm of the sea. The journey culminates at the Cove House Inn, strategically positioned to offer breathtaking views over a pint. Settling on the low wall outside the pub, the vast expanse of the ocean before you, there’s hardly a more fitting conclusion to a day spent exploring the Isle of Portland.

Happy discovery!
