Due to the natural shelter formed by the island of Portland and Chesil Beach, Portland Harbour has been a safe anchorage for shipping since ancient times. But it wasn’t until 1849, when work began on the Royal Portland Breakwater, that it became a harbour of refuge. The construction of the breakwater, during the Victorian era, became a visitor attraction as people flocked to see how the work was progressing.
Around the same time, other fortifications were constructed to defend the harbour, including the Verne Citadel (now a prison), the Verne High Angle Battery and Nothe Fort on the Weymouth side.
Portland Harbour was finally enclosed with the completion of the final two breakwater arms in 1906, making it one of the largest man-made harbours in the world.
