Thatching on the Isles of Scilly

Down Among The Sheltering Palms…

114aFrom looking at the images, of other tightly roped, thatched roofs on this site, the attentive reader might imagine the Victorian family posing below, to have known some Gaelic, or the lilt of the Isle of Man. But this family may well have spoken with a Cornish accent; living twenty eight miles, over the horizon from Lands End; in the Isles of Scilly…

Most of the images found on this page, were taken by members of the Gibson family, from St Mary’s. Several generations of which have recorded life on these islands; allowing us to look back and see how the thatching hereabouts differed so much, from that in the rest of Cornwall.


These images mainly date from the second half of the nineteenth century; showing a consistent use of roped thatch. So this tour of Britain ends, as it began on Shetland, with some thatching in the Highland tradition…

Yet the Channel Islands; further south and almost as exposed to Atlantic gales, use the Standard method of thatching. This difference, in style and method, was due entirely to a lack of resources. The islands that make up the Scillies, are much smaller than Jersey or Guernsey, and there was never enough surplus cereal straw to cover the roofs in a standard fashion. Importation was obviously too expensive. This, coupled with a windy climate, created conditions more common to the very north of Britain. The solution being the same roped thatch, renewed every few years; as used in these higher latitudes.

The islands roofing was commented on by various travellers. The Italian, Duke Cosmo, visited Scilly in 1669 and was intrigued by the cottages he saw. ‘The more common ones have a peculiar sort of covering…. having nothing but a simple mat spread over the rafters, drawn tight all round, and fixed firmly to the top of the walls. This they say, is the sort of covering commonly used in Bermuda, and it is necessary to renew it every year.‘ So it would seem that the thatcher’s art had changed little, in the two centuries until the Gibsons started their photographic record. I doubt if there was much influence, from Bermuda, on Scilly’s thatching, as his grace suggested; but ships and ideas may well have come from other directions.

In the century after the good Duke’s visit, a Mr Heath records a similar situation, in 1750. ‘…the method of covering is with a thin coat, when harvest is over, and they begin thrashing their corn’. A look at the photographs show that the roofs are not that thin, it would seem a top coat was added, as and when deemed necessary; not much old thatch being removed. Mr Heath also notes the method of roping used as ‘… straw rope crossing one another in a figure like the glass windows.’ The square shapes he suggests are visible on the pictures and refer to leaded window panes; a common sight, to an eighteenth century writer.

The best description of the thatching here, is found in A view of the present state of the Scilly Islands, by the Rev. George Woodley in 1822…
‘…there is something peculiar in the manner of thatching houses in Scilly, it may be observed that, owing to the great prevalence of boisterous winds here… the inhabitants are under the necessity of securing their roofs in the best manner their means will afford. For this purpose, they drive large wooden pegs into the chinks between the stones, about a foot and a half from the top of the walls, and but at a little distance from each other. Having laid on a sufficient quantity of thatch, they bind it down with straw ropes, fastened to the pegs before mentioned, extending from the front to the back of the house, and intersected by ropes of the same material running from end to end; so that, if the ropes hold the roof cannot be blown away without taking the top part of the wall! The appearance of these roofs, certainly, does not convey the idea of a ‘cottage orne’, but use and custom must justify the practice.’

Thatch existed on most of the islands, at the time of the Revered Woodley’s perambulations. In Hugh Town the largest settlement, on St Mary’s; ‘the walls are low, and many of them covered with thatch… occupied by mechanics, inn holders and tradesmen…’. The original church on St Martin’s was thatched, ‘20 feet long with walls 7 feet high’. And on Tresco, the ‘principal village… contains about a dozen houses… they are nearly all covered with thatch’.

Sadly the craft is now extinct on the islands. Slates and Bridgwater pantiles, brought in as ship’s ballast, spelt the end for the craft as the twentieth century progressed. The last thatch disappeared as late as 1990, on the island of Tresco. Now for the first time in their history, the islanders have to rely totally on imported materials; to keep themselves dry…


Fashion historians would love this picture, but to us the gent in the top hat, on the rick is of more interest. He seems to be in the process of thatching, over that years hay harvest. The hay itself is being used as a covering, not the best material, as it soaks up water as well as shedding it. Showing how limited the supply of better thatching materials must have been. Both ricks and houses are thatched with the same method, if not material.


A view of Old Town, St Mary’s. The roping down seems very professional, but this is not surprising, in a community used to ships and the sea. The straw ropes, mentioned by early writers have gone. A close proximity with the sea, in the age of sail, would have yielded a vast amount of, longer lasting hemp substitutes. The ends of the material, used around the chimneys, seem large and the thatch is quite long; this could be water reed, from small local reed beds.


An Edwardian view of St Mary’s. Beyond the flower strewn foreground, on the right, are two waterside thatches. Now in a minority hereabouts.


Old Grimsby, Tresco. The rot has set in and one family already sleeps under a roof of pantiles; perhaps not used to the change they have a horse shoe over the door for luck. A large piece of wood holds next door’s ropes secure against the tiles, maybe an old ships timber. They were used extensively, as timber along with thatch, was a scarce resource on many islands, both in the north and here, in the far south west of Britain……….

End of an era… ‘Tresco, June 1939’; a holiday snap taken a few weeks, before the Second World War ended such excursions to these islands… This boy’s family it seems, according to other photos, was adopted by a local fisherman and his cat. What is also of interest is the thatch, in the background.This could well be the fisherman’s home; or, given it’s poor state, his working hut. The thin layer of thatch is, as ever, roped down; some iron sheeting helps form a ridge. The craft of thatching would seem to be drawing to a close hereabouts…
