Does Blackpool Tower Sway? Yes—And It's Designed To

Yes, Blackpool Tower sways in the wind—and that's by design.

Structure & Engineering

• Height: 158 m (518 ft) – tallest structure in Blackpool.
• Materials: Steel and cast iron on a 2.7 m thick concrete foundation buried 12 m deep.
• Base diameter: 12.5 m (41 ft), tapering to 8.2 m (27 ft) at the top.
• Steel weight: 1,250 tonnes.

Why It Sways

A slender, free-standing tower of this height cannot be perfectly rigid. Controlled flexibility allows it to absorb wind energy without structural damage. Sensors continuously monitor deflection; the tower closes to the public if sway exceeds safety thresholds.

Visitor Experience

On windy days, guests at the Tower Eye observation deck may feel gentle movement—similar to a tall skyscraper. It's normal, safe, and a testament to Victorian engineering foresight.
