In the books
In the Song of Ice and Fire novels the Twins represents the only crossing point over the Green Fork for hundreds of miles in either direction, and is a major barrier to travellers and merchants travelling from the North to the western Riverlands. It lies directly athwart the main route from Winterfell to Riverrun. Moving from one castle to the other whilst avoiding the Twins requires a lengthy detour hundreds of miles to the south or hazardously traversing the bogs and swamps of the Neck to the north.

House Frey was but a minor house of the Riverlands until six hundred years ago, when the Freys built a stone bridge over the Green Fork, defended by two wooden castles at either end. Charging passing travellers for the use of the Crossing, they grew very wealthy, and replaced the wooden castles with strong stone ones, complete with portcullises, moats and barbicans. The bridge itself is covered, wide enough for two wagons to travel abreast and has its own tower, the Water Tower.
