Following my column about ancient reused timbers in house construction a few weeks ago, I’ve been contacted by a couple of experts who kindly took the time to put me straight on a few points.
Marine archaeologist and timber expert John Buglass was the first to correct an oft-repeated story:
“I am afraid that the reuse of ‘shipwreck’ in old buildings is a long held belief that has very little or no actual evidence. Several things to consider about ‘shipwreck’ timbers: firstly they are a wreck so are often badly damaged and salt affected (and often in remote locations); secondly if it was from a broken up ship at the end of its working life…then that is 30-40 years in a marine environment; thirdly, why would you go to great expense and time to haul timbers from the coast to an inland site when other closer sources would be available? That is not to say there aren’t some coastal buildings that have reused ships’ timbers but they are very few in number.”
So the romantic story that I have perpetuated is a load of old cobblers. How disappointing! I have a feeling my dad would be raising an eyebrow at me from above for not having dug a little deeper. I am always happy to be corrected by people with more expertise than me though!
John added: “We are only too familiar with the claim of many historic property owners that their house is made from ships’ timbers, despite the fact that it is located many miles from the nearest navigable waterway, let alone the coast. But this does little to dissuade the long held and cherished belief…This even extended to an inspection of Wordsworth’s Dove Cottage which could plausibly have had timbers from boats operating on nearby Grasmere, but sadly this was not the case. There are, of course, the exceptions which prove the rule. Probably the most extensive example is Chesapeake Mill on Bridge Street in Wickham, Hampshire. This Grade II* listed building is substantially built from American longleaf pine from the dismantled remains of the American warship Chesapeake which was captured in 1813 by HMS Shannon and dismantled in Portsmouth in 1819.”
He continued: “Hauling large timbers from the coast into the Dales is true in some cases…some large timbers in 19th century buildings have what are known as Baltic timber marks. These are from large timbers shipped across from the Baltic where the forests still had large trees that could be used for substantial buildings. They would have come into ports such as Hull and been hauled inland on oxen carts. But these are new timbers, not reused ones. The marks are a code for where and who supplied and shipped the timbers, but I’m not sure how they are decoded.”
John agreed to look at the marks on the timbers I featured in my article, but I will save his comments for a future article.
Jim Coulson is a wood scientist and member of the International Wood Committe of the International Council On Monuments and Sites. He has a spent more than 30 years working with timber and backed up John’s comments:
“The reuse of old timbers is a common thing to have done, but almost never from ships – that is just an Old Wives’ Tale. Most ships’ timbers were the wrong dimension and shape for building houses, and it was far more common to reuse timbers from barns or other disused buildings.”
He added: “Reused beams are found in many older properties, but it is usually impossible to say where they came from…Identification of such beams is possible as to wood species, but their origins would be almost impossible to pin down without some sort of documentary evidence.”
As for the marks I noticed on the beams in ‘my’ house, he states: “The marks…are usually carpenters’ marks, often used to identify the particular craftsman, but sometimes, in very old mediaeval buildings, they were used to ward off evil, and known as ‘witches’ marks’.”
I’ve written about witches’ marks myself, and my dad was an expert, his theory being that some were connected to Catholic martyr Father Nicholas Postgate.
Were they, as Dad believed, a decoy to fool Catholic persecutors into thinking that a safe house was occupied by pagans rather than treasonous Catholics?
