The 18th century windmill
'De Haensmole' at Grou (Friesland) was destroyed
on 9th Jan 2004, when it was rammed by the empty 85m long tanker Renasa.
The mill had only just completed a restoration in 2003.
The Dutch Mill database
has some photos, and there is a
photo of the wreckage, but I don't know how long it will be available
for since the story has already dropped off this site. There is an
illustrated article,
and another.
Other sites carry the story in Dutch if you can read that - they all seem
to be reporting the same agency story:
