A 5000 year old door was found during an excavation in Zurich, Switzerland yesterday. It is apparently Poplar, and the first complete door made of seperate boards they have found of this age that could date back to 3,063 B.C They say what is so remarkable about it, besides being a complete door 5000 years old, is the way the planks were held together. I’m still trying to make out the joinery from the larger photo, but its a little dificult. It looks like a board is woven on the top and bottom.

Here is the article with a picture of it. I’d love to see it in its original beauty. They said they would put it on display after its soaked in a chemical solution to prevent rotting. I wonder if they will restore it lol.

It’s amazing that it had not rotted away by now.

Funny one Neil, it may need a few years to air dry lol. Gee I hope it doesn’t warp while drying ;)

No problem, I thought fellow LJ’s would enjoy this article.

Helluvawreck, amazing isn’t it. I think its from the climate at that time in that area. It probably just froze.

Can anyone discern its joinery? I’m still trying to figure it out.

Yeah, poor journalism. They say no fewer than twice that the door has “remarkable” joinery, then they say nothing about that joinery. It almost looks like iron or leather straps.

Anyhoo, my bet is that this is the door to the bar “Oetzi” got kicked out of on the night of his untimely demise.

Construction looks to be based on cleats.

The two support boards appear to be affixed to the three main planks by means of three sets of dual holes and a short bent length of wood. Instead of glueing the cross braces to the planks directly they appear to have worked out a solution that would let them expand in opposite directions without splitting.

Scary that they understood wood movement (at least at some level) over 5,000 years ago.

JJohnston, I think we’ll have to wait for it to be cleaned up for more details about the joinery, maybe FWW or other wood magazines can get some time up close with the door and do a neat article about it. Right now though its just an exciting find. I’m guessing the archeologists were probably just blown away that the door had any kind of joinery instead of the solid wood doors they’ve been finding from that time.

Thank you guys for explaining some of the joinery you are seeing, I know its hard to actually tell though.

Okay – How do they know it was made in 3063 B.C.? Is that date marked on the door? Note – In the B.C. people did not know they were in the B.C..

They’ve got tree ring dating down surprisingly well. Looking at one tree will tell you how old that tree was, but it won’t fix it in time. However, they have tree ring records starting at the present and working backwards. Good and bad growth years reflected in the rings can actually be overlapped from tree to tree, and that fixes a tree’s lifetime relative to the calendar. Am I making sense?

Rich honestly I have no clue but it’s coming directly from the archaeoligists so I’d say its at least relatively accurate. I know that they can compare it to other previously dated finds to find a relative age (besides doing more advanced tests), but after re-reading the post I modified my wording to match theirs. I thought it said it was from 3,063. It actually says …”Using tree rings to determine its age, Bleicher believes the door could have been made in the year 3,063 B.C. “

yah again those juenalist just donĀ“t listen they writte what they think they heard
and only based on the first two minuts of the what is said
they can easely determ what age wood has with the coal 14 test metode (excuse my bad translation of the metode) but they have to make more advanced test before they can say it excacly precise

thank you for sharing this wonderfull door with us
ceep us updated about the metode they used to make the door please :-)

take care
Dennis

You mean carbon-14? I think the tree-ring method is much more accurate, provided they have an unbroken line of ring data going back that far.
