From one of the news articles on tma:
"Around half to two-thirds of the original timbers and the central stump of the Seahenge circle will be at the [kings lynn] museum from early 2007. All the timbers from Seahenge, which made national headlines in 2001, will be at the museum but there won't be room to display the entire circle, although the final display sizes have yet to be finalised. The timbers are currently with the Marie Rose Trust in Portsmouth where work is being carried out to permanently preserve them so they can go on display. The treatment involves soaking the timbers in a wax substance before they are vacuum freeze-dried – a time-consuming process."
