River Farset

Rising on Squire's Hill on the north-western edge of Belfast, the River Farset is on the County Antrim side of the Lagan, and its entry to the Lagan is close to that river's outflow into Belfast Lough.

[1][2] The Farset is now contained within a tunnel under Belfast's High Street supposedly big enough to take a bus.

[3] Belfast was founded at a sandy ford across the Farset, and this is the origin of the city's name – Béal Feirste, the "river mouth of the sandbar".

The river flowed beside docks on High Street as Belfast grew in the 19th century.

[4] Over the course of the 18th century it was gradually covered over; the final section, close to Princes Street, was culverted in 1804.
