History
Origins and construction
Fort Perch Rock is a former coastal defence installation in the United Kingdom, at New Brighton on the mouth of Liverpool Bay. Built between 1825 and 1829 to defend Liverpool and Birkenhead, it emerged from fears of a French invasion during the Napoleonic Wars. Liverpool merchants proposed a fort at New Brighton in 1803, although debates over how to finance it continued for many years.
The foundation stone was laid on 31 March 1826. Its inscription names Captain John Sikes Kitson of the Royal Engineers as the person who projected and directed the work. The Royal Engineers were the British military corps responsible for fortifications and related engineering projects. The inscription also names Peter Bourne, Mayor of Liverpool, and the Duke of Wellington as Master General of the Ordnance during the reign of George IV, who was king from 1820 to 1830. The fort had originally been proposed as a fortified lighthouse to replace the old Perch Rock Light, but a separate lighthouse was constructed instead.
Military use and alteration
Fort Perch Rock was occupied as a defensive installation and fired its guns twice. At the beginning of the First World War, the river entrance was declared closed and the fort fired on a Norwegian sailing ship. The shell passed over the vessel and landed at Hightown on the opposite side of the Mersey without exploding.
By the 1890s, the original guns were obsolete. Alterations made between 1894 and 1899 introduced three six-inch guns, an observation and firing post on the eastern tower, and a large searchlight for illuminating the river mouth. The sea-facing walls were also lowered during these works, reducing their height by 15 feet.
Decommissioning and later interpretation
The Ministry of War decommissioned the fort in 1956, after which it was sold to the Darroch family. It now functions as a museum and has hosted exhibitions and cultural events, including musical concerts. Its displays address military aviation and maritime history, while a former marine radio museum presented equipment used for wireless communication at sea.
Fort Perch Rock is a Grade II* listed building in England, a designation for a building of particularly important architectural or historic interest. The listing was made on 4 January 1977. Its place in local cultural memory also appears in Letitia Elizabeth Landon’s poem The Black-Rock Fort and Lighthouse, written as a poetic illustration of an engraving after a painting by Samuel Austin. The poem imagines the lighthouse beacon welcoming voyagers returning to England.
Remains
Layout and construction
The fort occupies about 4,000 square yards, approximately 3,300 square metres, on Black Rock. Red sandstone from the Runcorn quarries was laid on a sandstone-rock base. The walls rise between 24 and 32 feet, while the round corner towers reach about 40 feet. The installation was designed for 100 men, in addition to officers, provisions, and armament.
Fort Perch Rock originally stood in an area surrounded by water at high tide. At low tide, it could be reached on foot across the beach. A bridge now connects it with the mainland, and later coastal reclamation made the fort fully accessible.
Defensive structures
Entrance and walls
The original approach crossed a drawbridge and passed through a Tuscan portal, a classical-style entrance, carrying the coat of arms and the words “Fort Perch Rock.” The fort’s substantial sandstone walls and rounded corner towers formed its principal defensive envelope.
Original gun positions
The fort originally carried 18 guns, including 16 32-pounders mounted on platforms. A 32-pounder was a smoothbore cannon named for the weight of the solid iron shot it fired. The guns were concentrated mainly along the northern and western sides, covering the principal shipping entrance to the Mersey. Passing vessels came within less than one kilometre of them.
Late-nineteenth-century defences
The alterations of 1894 to 1899 placed three six-inch guns in a new emplacement in the inner courtyard. A six-inch gun was classified by the diameter of its bore. The eastern tower received an observation and firing post, and a large searchlight was installed to illuminate the river mouth. The sea-facing walls were lowered by 15 feet as part of the same defensive changes.
Perch Rock Lighthouse
New Brighton Lighthouse, also called Perch Rock Lighthouse, stands beside the fort. It was built as a separate structure rather than as part of the fort’s original scheme, and it no longer serves a maritime function.
