Seaforth Battery, Seaforth, Merseyside, England. was built to protect shipping on the River Mersey. Constructed as part of the defences of the Mersey Docks, the battery was designed to engage ships using the Rock Channel head on as well as the other shipping channels. The battery supported Fort Perch Rock, which was located opposite on the Wirral bank of the river.
In 1875 a battery of seven saluting guns was erected in the fort. Four 12.5-inch RML guns were installed but were soon removed and replaced in 1894 with two 4.7-inch Quick Fire guns which were originally sent to arm Fort Perch Rock. These were suitable for engaging fast torpedo boats. In 1898 a fire control centre for the 4.7-inch guns was added at the east end of the battery. In 1907 two chambers were opened out to mount searchlights. The salting battery was removed in 1911.
In 1923 the rear of the battery was removed as the docks expanded. In 1928 the battery was dismantled to be relocated at the Crosby Battery and the site was cleared in 1929.
