One of the gun emplacements for the High Angle Battery on the Heights, Portland. The best preserved example of its kind and a scheduled ancient monument, the Verne High Angle Battery was built in 1890 to protect Portland Harbour with six 9 inch Rifled Muzzle Loading guns on carriages designed to enable them to fire at very high anglee, allowing them to drop shells onto the less protected upper decks of ships. This is one of six emplacements. Pohotgraphed on 13th July 2021 and reconstructed in Agisoft Metashape from 35 images.
