During our last photoshoot at Landguard Fort in Felixstowe, we noticed the cobblestones in the main entrance seemed mis-matched. The ones on the right looked like old cobblestones, but the ones on the left looked to be much newer, and made from wood.
We asked one of the tour guides why there were wooden cobbles, and he told us that during wartime the main entrance was used for bringing in ammunition. The carts used to carry the ammunition had steel wheels, and if the cobbles were made of stone then there was a risk of sparks igniting the ammunition. They also had the added benefit of dampening the sound of carts and troops passing through.
"Then why does only half of the walkway have wooden cobbles, and the other half have stone ones?" we wondered.
"They are all wooden," he replied, "the ones on the right are just older".
On closer inspection it was obvious, the grain clearly visible. The cobbles on the right had been there since the 18th century, and had been worn in a way that made them look like stone. They had small bits of gravel pressed into them over the years, and were even cold to the touch. The cobbles on the left were much newer, a mere 100 years old. It was another reminder of what an amazing, versatile material wood is.
