An imposing building of national importance forming the centrepiece of an industrial complex located on Deep Water Berths Road in Sligo Town. An innovative construction system developed by François Hennebique (1842 - 1921) in 1892 was used in the design of this warehouse.The builiding is one of the earliest surviving examples of the Hennebique system in the island of Ireland. Advanced construction techniques are masked by rendered details, producing a strikingly Modern geometric design, a distinctive feature in the landscape of Sligo Quays.
