Lambeg (historically Lanbeg, from Irish Lann Bheag 'little church')[1] is a small village and civil parish in County Antrim, Northern Ireland.

The earliest documentary evidence of the textile industry in Lambeg records the setting up of a bleach green in 1626.

By 1760, Mr John Williamson owned most of the village and played a prominent role in the development of the linen trade, through ownership of the Lambeg bleach green.

The Wolfendens were another foreign family who went into exile in Lambeg and assisted in the establishing of the manufacture of linen cloth in the village.

[8] Leigh's New Pocket Road-Book of Ireland, published 1827, states:[9] The rich bleach-greens of Lisburn and of Lambeg, a pleasant village, with a pretty church beyond it on the Belfast side, together with the mansions of opulent linen merchants, here attract attention.In 1920 the Government of Northern Ireland set up a "Linen Industry Research Association" (LIRA) in Glenmore House, a 17-18th century manor house,[10][11] for the scientific and technical research of textiles, especially linen.

Due to the decline of the industry the centre closed in 1993, although its library of books and journals are now housed in the Lisburn Museum.
