Adding on:
Arsenal were founded as Dial Square in 1886 by workers at the Royal
Arsenal in Woolwich, but were renamed Royal Arsenal shortly
afterwards. They renamed themselves again to Woolwich Arsenal after
turning professional in 1891. The club joined the Football League
in 1893, starting out in the Second Division, and won promotion to
the First Division in 1904. However, the club's geographic
isolation resulted in lower attendances than those of other clubs,
which led to the club becoming mired in financial problems. In
1913, soon after relegation back to the Second Division, they moved
across the Thames to the new Arsenal Stadium in Highbury, North
London. They dropped "Woolwich" from their name the following year,
thus becoming one of only two Football League teams not named after
a place, the other being Port Vale. (info from Wikipedia)
