HMS Monitor M33 stands in Portsmouth’s historic dockyard, a rare surviving example of a First World War monitor warship. Built in 1915, the vessel served the Royal Navy during the Great War and beyond, earning a place as one of only a handful of monitors still in existence. The ship is preserved in a dry dock where visitors can explore both the interior and exterior decks, offering a tangible connection to early twentieth-century naval engineering and warfare.
The monitor is accessible via a lift that descends into the dry dock, with step-free access through the ship’s interior spaces. Visitors should note that access to the outside decks requires climbing steps, and whilst the site offers limited wheelchair facilities, an accessible toilet is not available on-site. The vessel remains a significant maritime heritage attraction, drawing naval history enthusiasts and curious explorers keen to understand the role of monitor-class warships in shaping modern naval combat.
