Does anyone have any information about the life of upper class Irish people in the late iron age (circa 200-400 a.d)? I've read a source that says wealthy houses in this time were in a figure of 8 shape, had plastered walls and were made of solid wood planks rather than wickerwork, is this accurate? Thanks in advance. Any information on clothing and the chariots of the time would be very useful.
Although its a few centuries past your time frame you might like /u/depanneur's answer to:
How did Irish kings live in the early middle ages? (600 a.d - 900 a.d)
The FAQ on Celts/Gaels will probably also help.
