It produced a variety of products - from small to large. This included the manufacture of locomotives and bridges, as well as some shipbuilding. In the 1860s, the foundry produced the diving bell used in the extension of Dublin Port, which is now on display on Sir John Rogerson's Quay.[1][2][3]

Bridges

edit

The firm was a noted bridge builder, and its works included the 1869 lattice iron Obelisk Bridge over the River Boyne[4] and Dominic's Bridge in Drogheda in 1863.[1]

Between 1845 and 1885 the company produced about 50 locomotives, mostly for the Irish Broadguage system but also at least one for Brazil.[1][2][5]

Reopening

The foundry was re-established in 1914 as the Drogheda Ironworks and had employment for up to 70 people until closure in 1970.[1]
