Named after the heart of the Royal Arsenal complex, they took the name of the whole complex a month later. Royal Arsenal F.C.'s first home was Plumstead Common, though they spent most of their time in South East London playing on the other side of Plumstead, at the Manor Ground. Royal Arsenal first trophies they won was the Kent Senior Cup and London Charity Cup in 1889–90 and the London Senior Cup in 1890–91 these were the only football association trophies Arsenal won during their time in South East London.
