Coquimbo Football Club was founded in 1896, and merged in 1957 with Coquimbo Unión F.B.C. to form the present Coquimbo Unido. It is one of the oldest clubs in Chile. The club's logo, adopted in 1962, is a shield quartered yellow and black, with a drawing of a pirate's head in crest. The supporter's groups wave flags in the team's livery colours. It is loosely based on the Coat of Arms of Spain. Alex Garofolo, 4 February 2016 Source: C.U. Official Website
The gold and black (orinegro) colours were officially adopted on 23 September 1912; these colours originally belonged to "Alianza F.B.C.," a club founded in May 1912 in Coquimbo. These colours were indeed those of the team of the cruiser HMS Flora, defeated in 1903; the team used the colours of the Welsh town of Pembroke, where the ship had been built in 1891-1895 and the origin of most of the crew. The arms of Pembroke are "Or a bend sable charged with a dragon of the first cantonned by two lions of the second." C.U. Official Website: History, Chapter II
