Interpreting the evidence
The experimental reconstruction was possible due to the thousands of timbers recorded at Oakbank Crannog representing uprights, floors, and woven hazel hurdles. The juxtaposition and volume of these timbers demonstrate that this early Iron Age crannog was built initially as a free-standing dwelling supported by stilts or piles.
'... fibrous plants were used to make ropes for lashing timbers ...'
Analysis of the hazel hurdles indicates that the crannog farmers were also woodland managers. They coppiced hazel and other native species to provide a regular supply of timber for structural needs, fuel and domestic utensils. The well preserved tool marks on a range of timbers were the subject of a separate research project, and suggest the use of iron rather than bronze axes, knives and other tools.
There was also evidence that fibrous plants were used to make ropes for lashing timbers, tethering animals and carrying goods. Analysis of the abundance of bracken in the site showed it was harvested all year round. It would have been used to make the floor more comfortable and warm, to make the walls draught-proof, to provide animal and human bedding, and probably to help thatch the roof.
Finds of charcoal, ash and sizeable stones near the middle of the house may represent part of the central hearth, where the fire would have been in almost constant use for cooking and heating the building.
