Botany Mill / High Mill, Roxburgh Street

Botany Mill is a rare surviving “slow loom” mill and a prominent remnant of the industrial quarter that grew around Roxburgh Street and Botany Lane.

Quick Facts

From Weirhaugh to Botany Mill

The site has a much longer manufacturing history than the surviving building alone suggests. The National Record of the Historic Environment, drawing on Robert Hall’s 1898 history, records that Hugh Sanderson, clothier, and Thomas Clapperton, weaver, erected a mill here in 1797. It was originally known as Weirhaugh Mill. The first building was modest by later factory standards, measuring about 40 feet long and 18 feet wide, but it belonged to the early phase in which Galashiels was moving from dispersed hand production towards mechanised manufacture.

The works were enlarged in 1829 with a spinning mill. This sequence – fulling first, then spinning and later weaving – reflects the increasing concentration of textile processes in purpose-built industrial premises. The eighteenth-century and 1829 buildings have not survived.

Why “Botany”?

HES and the national record both preserve the explanation that the name arose because this was the first Galashiels mill to use Botany wool. “Botany” was a trade term associated with fine merino wool imported from Australia, rather than a reference to plants or gardens. HES phrases the explanation cautiously, and the precise date at which Weirhaugh became known as Botany Mill is not established.

Fire and Reconstruction

A serious fire in 1870 caused damage recorded by Hall at £10,000, a very substantial sum at the time. HES considers that the fire most likely destroyed the earlier mill and dates the present building to about 1870-80. The surviving high mill was built for Sime Sanderson and Co.

This chronology places the rebuilding close to the late-1860s and early-1870s peak of Galashiels’ textile prosperity. The railway had reached the town in 1849, improving access to coal and raw materials, while steam power became increasingly important during the 1860s. Botany Mill is therefore a physical product of the moment when the town’s industry was becoming larger, more mechanised and more closely connected with distant markets.

A Slow-Loom Mill

HES identifies Botany Mill as a rare survival of a “slow loom” mill. Before fast looms became established from about 1880, weaving could be accommodated on several floors of a high mill. The surviving building preserves that vertical factory form at the point when industrial design was about to change.

The four-storey mill has a regular six-bay frontage and is two bays deep, with a canted bay at the southern corner. Whinstone and sandstone rubble walls are picked out with red sandstone dressings. The purple-slated M-roof has a central valley gutter. Inside, HES records cast-iron columns, timber beams and a timber stair, although later subdivision has altered the working floors.

The combination of repeated windows, multi-storey height and robust internal framing was practical: it provided light and carried the loads of machinery, materials and production. It also gave the mill a powerful presence in the townscape.

An Industrial Group

Botany Mill should not be read in isolation. HES groups it with the neighbouring Morrison and Murray Engineering Works and the former Glasite Meeting House. Together these buildings bring different strands of Galashiels’ history into a remarkably compact area: textile manufacture, the engineering trades that supported an industrial town, and a distinctive dissenting religious community.

The relationship also helps explain why the survival of each component matters. Even where individual buildings have changed use, their proximity allows visitors to understand Botany Lane and Roxburgh Street as an industrial and social landscape rather than as a collection of unrelated structures.

Later History

Multi-storey weaving mills were overtaken by broad single-storey sheds as faster looms changed the requirements of production. HES records that Botany Mill was marked as a wood store when sold in 1932, showing that its original textile role had already changed. The present building has since accommodated other uses, but a reliable description of its current internal occupation has not yet been confirmed for this directory.

Why It Matters

Botany Mill is valuable because it preserves evidence from several connected phases of Galashiels’ growth. The site reaches back to an early fulling mill of 1797; the surviving building records post-fire reconstruction during the town’s industrial peak; and its slow-loom form captures a type of mill that was soon superseded.

It also contributes strongly to the identity of the Botany area. Alongside the engineering works and Glasite meeting house, it makes visible the close relationship between work, technology, belief and urban expansion in nineteenth-century Galashiels.

Things to Notice

• The four-storey height and disciplined rhythm of six window bays
• The canted bay at the southern corner
• Red sandstone dressings contrasting with darker rubble walling
• The M-shaped roof and concealed central valley
• The way the mill closes views and marks the industrial character of Roxburgh Street
• The short walking relationship with the former Glasite Meeting House and Morrison and Murray works

Timeline

• About 1870-80: present high mill probably erected for Sime Sanderson and Co.
• From about 1880: fast looms begin to supersede the type of multi-storey weaving mill represented here

Notes and Uncertainties

• The surviving high mill is probably of about 1870-80. HES does not give a single documented construction year.
• The 1797 and 1829 buildings were predecessors on the site and should not be confused with the present structure.
• The traditional explanation of the Botany name is repeated by HES and the national record, but the date of the name change is unknown.
• Hall’s £10,000 fire-loss figure is preserved through the National Record of the Historic Environment; it has not been independently recalculated or converted to a modern value.
• The building’s current use and interior condition require local confirmation.
