Historic Fortifications

Located in the northern part of Portsmouth are a collection of Forts known as the Hilsea Lines. Originally constructed in the 18th century to defend the city and its crucial naval yard from land attacks, the Hilsea Lines we see today showcase 19th century architecture and equipment, as the forts were modernised to incorporate artillery technology. Multiple areas of the forts were improved, including the moats and ramparts. The lines were built stretching from Portsmouth Harbour to Langstone Harbour, strategically cutting off any mainland approach to the city.

Despite heavy investment in modernisation and perhaps as a testament to the imposing might of Portsmouth’s navy and its multiple land and sea-based fortifications, the Hilsea Lines never saw direct combat. By the 20th century, the threat of land attack had subsided, causing the forts to fall into disuse.

A Great Place to Visit

Today, the structures have been transformed into wooded green spaces, providing nature trails, lakes and a recreational space for locals and visitors. The area is now a designated nature reserve and is home to numerous species of birds, insects and mammals. History enthusiasts can still explore some of the old structures, ramparts and tunnels, enjoying a unique perspective in to the local military history.
