Ignatius Bonomi (1787-1870) was an English architect and surveyor, with Italian origins by his father, strongly associated with Durham in north-east England.
Ignatius's work (he was Surveyor of Bridges for the County of Durham) included one of the first railwaybridges in the UK (over the River Skerne, near Darlington), for the Stockton and Darlington Railway, in 1824 (hence he is sometimes referred to as 'the first railway architect').
He was also responsible for a number of church buildings (including commissions at Durham Cathedral). Other historic buildings, in Gothic and neo-classical styles, included Durham Castle, Lambton Castle (continuing the work started by his father), Durham Prison, Elvet Hill House (1820), Burn Hall and Eggleston Hall, all in County Durham. In Derbyshire he designed Christ's church King Sterndale near Buxton, built 1848/1849 for the Pickford family, founders of the Pickfords Removals business.
His brother, Joseph, designed Temple Mills in south Leeds for John Marshall, modelling it on the Temple of Horus at Edfu in Egypt. To insulate the roof in order to ensure the correct humidity for flax spinning, a layer of plaster was covered with pitch. Earth was shoveled on top to prevent the pitch cracking and grass was seeded to bind the earth together. A small flock of sheep was kept on the roof to keep the grass down.
In 1831, Bonomi took on John Loughborough Pearson as an apprentice. In 1842 he entered into a partnership with John Augustus Cory, later Cumberland County Architect (from 1862). The church of St John the Evangelist, Nenthead (1845, the highest church in England) was one of their joint projects.
