The Lower Lines Park, also known as the Admiral's Gardens, is part of The Great Lines defensive fortification (Chatham and Gillingham). The site had military uses from its construction in 1803 to the Mid-20th Century. It owes its name to a house, built in the later 19th Century, to provide offices and accomadation for the Admiral, his family, and staff. The house and its gardens were in use until 1959 but were eventually demoished in the 1960s. The park was revitalised in 2010 by clearing overgrown areas and installing tarmac paths, benches, and a childrens play area.
