As far as building materials go, wood is supposedly pretty strong. Even car bridges can be made out of them. I can’t provide a cite. I’ve heard it in numerous places.
So what is the oldest wooden structure that is still standing?
Also, this next one is going to sound a little weird. But back when I was a little kid, we used to go to this wild west theme park. It was educational too. Anyways, they used to have these fake tombstones made of wood. The reason given was that it was a fad of its time. Stone tombstones were rather pricey. So some people just had ones made of wood.
Are any of these still standing? I mean the writing would be all faded. But still. When was the last one of these extant?
