I was working from 6/2000 until 5/2023 as a director of Kierikki Centre and was active in EXARC meetings and OpenArch-project. I have not specialised to handicraft (my speciality is landscape history + long history in museum works) but since the early 90's dozens I visited dozens archaeological open-air museums around world. I have just retired and plan to make a popular book about the fine work EXARC members do and how fast this work has developed.
