The Banks Peninsula is a remarkable geological formation that results from the merger of two ancient volcanic islands, now joined to the mainland as a result of the formation of the Canterbury Plain, on which Christchurch is located. The Plain is mostly gravel washed down over a very long time from the Southern Alps, the backbone of South Island, by many rivers. The ancient volcanic craters were invaded by the sea and now form Lyttleton and Akaroa Harbours. Christchurch has a beach (New Brighton) but no harbour of its own, so Lyttleton has served that role from the earliest settlement of Christchurch in the 1840's. Akaroa was settled by the French, but word of their impending arrival reached the British settlers in Canterbury, who got there first and planted the British flag.
