Thrupp was established as a parish in the Frome Valley in 1894 from an area that was previously part of Stroud. It included the hamlets of Upper and Lower Bourne, Lower Lypiatt, Quarhouse, The Heavens and Claypits as well as the village of Brimscombe. The modern parish is known as Brimscombe and Thrupp.
Phoenix Iron Works
Early records indicate that there was a cloth mill at Thrupp dating back as far as 1381. By 1770 the premises had expanded to include a house, four fulling mills and a gig mill.
The gig mill, which eventually became known as Thrupp Mill, was leased to Edward Ferrabee in 1793. By 1828 the entire premises were leased to the Ferrabees, and an iron works, the Phoenix Iron Works, had been established. The Ferrabees became well known for their production of cloth-making machines, steam engines, agricultural machinery and water wheels. It was here that John Lewis had invented a machine in 1815 to shear the surplus fibres or nap from the surface of cloth, using a horizontal blade.
In the 1820s Edwin Beard Budding, a machinist or "mechanician", was employed by Edward's son, John, at Thrupp. It was while Budding was working at Thrupp that Lewis' machine was developed to use rotary cutters, and Budding realised that this machine could be adapted for other purposes. Using gears, a revolving horizontal shaft and three blades he developed a machine to cut grass, which until then had been cut manually, using a scythe. This resulted in the world's first lawn mower being invented at Thrupp. It received its patent in 1830. Budding is also credited with the invention of the screw adjustable spanner.

Brimscombe Port was originally built to transfer cargo from Severn trows, which travelled from the River Severn down the [[wikipedia:Stroudwater Navigation, to Thames barges which carried the goods eastwards towards London. This was necessary because the locks to the east of the port were too narrow to accommodate the larger sea-going trows. There were also several boat-building yards at the port, including Abdela & Mitchell, who exported boats, notably paddle steamers, all over the world.
Many of the Abdela & Mitchell river-boats went to the Nile, the Niger and other African rivers, and especially to the Peruvian Amazon and other Amazonian tributaries. The Abdela river-boats were highly regarded for their elegance, shallow draft (often less than 40cm), and flexibility, viz the Adis Ababa for Lt-Col John Harrington's White Nile/Ethiopia expedition of 1903 – "boiler arranged to burn oil, coal or wood". The Shipyards announced themselves as "Contractors To The Admiralty, War Office, India Office And Allied Governments". (For references, see Wikipedia.)
Until the construction of what is now the A419 road along the bottom of the valley in 1815, Thrupp Lane was the main thoroughfare between Stroud and Chalford. The condition of this road was such that it required a whole day for a team of horses to draw a loaded waggon and return, a distance of only four miles each way.
Wikipedia also contains a list with brief descriptions of a number of mills of various sorts that existed in Brimscombe and Thrupp.
