Fortifications of Portsmouth, Military fortification system in Portsmouth, England
The Fortifications of Portsmouth form a network of stone towers, ramparts, and defensive walls spread across the coastline and Portsea Island. These structures represent different periods of construction and display various military engineering approaches.
The fortifications started in 1212 with a wall around a shipyard and expanded later during Henry VIII's reign with structures like Southsea Castle. These additions were built to protect the coast from attack and invasion.
The fortification sites host educational programs throughout the year, allowing visitors to learn about British coastal defense strategies across centuries.
Different sections are open at varying times, so check specific times for each structure before visiting. It helps to explore with a map, as the complex spreads across a large area.
The Round Tower was rebuilt between 1418 and 1426, transforming from a wooden structure into stone architecture. This change reflects how defense technology evolved as threats to the coast changed.
