Verne High Angle Battery

Verne High Angle Battery is a gun installation built into a former limestone quarry on Portland, featuring six firing positions and two underground magazine tunnels. The entire structure uses the natural rock formation, allowing the positions to aim at steep angles onto approaching vessels.

Built in 1892, this installation became part of England's harbor defense system using artillery designed to fire steeply downward onto enemy ships. It reflected the military engineering advances of the late Victorian period in protecting strategic coastal positions.

The site shows how Victorians built military structures to blend with the landscape, and you can sense their approach to coastal defense through the layout. The gun positions and underground spaces reveal the practical thinking that went into protecting the harbor from threats at sea.

Access the battery through marked paths near Verne Citadel, with guided tours offered during warmer months. The site has some steep sections and underground passages, so wear comfortable shoes and allow time to explore the tunnels properly.

In the 1960s, the tunnels served as testing grounds for nuclear material transport containers, showing the site was repurposed beyond its original military role. The isolated setting of the former quarry provided a secure environment for scientific experiments.
