Nab Tower, Sea fort and lighthouse in Solent, United Kingdom
Nab Tower is a 27-meter-high lighthouse and sea fort built on Nab Rock in the Solent. The structure serves as a navigational aid and defensive installation for passing vessels in this busy waterway.
Construction began in 1918 as part of a defensive network against German submarines during the First World War. The larger project was never fully completed despite initial plans.
Trinity House oversees this structure, which reflects the traditions of British maritime engineering and naval defense. Its presence shapes how people understand the Solent as a vital shipping corridor.
The tower emits two white flashes every 30 seconds and remains visible up to 12 nautical miles away. This helps ships navigate safely through these busy waters and shipping lanes.
Solar panels were installed in 1995, making it an early pioneer in renewable energy among British lighthouses. This modernization demonstrates how traditional maritime structures adapted to new technologies.
