Seymour Tower

Seymour Tower is a square granite structure positioned on a rocky tidal island roughly 2 kilometers from Jersey's southeast coast. The solid stone construction offers views across the coastline and surrounding waters from its upper levels.

Built in 1782 under Sir Henry Seymour Conway's direction, the structure was part of a broader defensive network following a 1781 attack on Jersey. Its construction represented a strategic response to reinforce the island's maritime protection.

The tower holds significance as a landmark that changes its accessibility with the tides, making it a distinctive destination for those who understand the sea's rhythm. Local guides often mention how this site connects visitors to Jersey's maritime heritage in a tangible way.

Visiting requires advance booking with an accredited guide due to the challenging conditions created by weather and tides. The best opportunity to visit occurs during lower tide periods when the island is more safely accessible.

The structure differs from other Jersey coastal towers through its square design and placement on a tidal island that submerges twice daily. This extreme tidal dynamic makes it a rare example of engineering built to withstand challenging natural forces.
