Fort Nelson is an impressive historic Victorian military fortification, standing majestically on Portsdown Hill in Portsmouth, United Kingdom. This fort is one of the five so-called "Palmerston Forts" on Portsdown, built in the 19th century to protect Portsmouth's strategically important naval port and dockyard from potential attack from mainland Europe, specifically France. The fort was named after the legendary Admiral Horatio Nelson, the hero of the Battle of Trafalgar.

Today, Fort Nelson has been transformed into a fascinating museum and is part of the famous Royal Armouries. Built of brick and stone and supplemented by powerful earthworks, this massive structure is a prime example of military architecture of its time. The fort is part of a ring of fortifications that once surrounded Portsmouth, protecting the city and its dockyard, located just 8 kilometers away.
Visitors to Fort Nelson can explore its imposing casemates, tunnels, and gun positions, as well as view the extensive collection of artillery from various eras on display. The site breathes history and offers a unique opportunity to immerse yourself in the United Kingdom's military past, while also enjoying panoramic views of Portsmouth and the Solent from the hilltop.
