Ignatius Bonomi (1787–1870) was an English architect and surveyor, with Italian origins by his father, strongly associated with Durham in north-east England.
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.
Until 1850 he lived in his modest stone villa in Durham City, now the Oriental Museum.[4]
