The article notes that the closure would happen on 1 Jan 13. Since that date has passed, it would seem something must've changed? Minister of Culture Jet Bussemaker suggested in a debate that Huis Doorn might be eligible for subsidy for projects on the First World War.
"If the plans of the Netherlands' recently elected coalition government are implemented, House Doorn will close its doors to the public on 1 January 2013. The country's cultural advisory body, which oversees the manor house and its 15-acre estate, has decreed that it "is not Dutch enough" to warrant its ¤441,000 (£354,000) in annual funding. As part of its austerity budget, the Dutch will cut that down to ¤216, 000, a measure that will force the closure of the house as a museum. "We will not be able to keep the house open to the public. Within a matter of years, the place will be forgotten and I fear that this will be used as a pretext to get rid of the vast collection of photographs and thousands of priceless royal artefacts," Mr Goossens said ."
The official website notes nothing of any potential closing--it lists its operating hours as normal.
The vote took place in late December and Huis Doorn, and another museum, didn't get good news. A proposition of three parties to create an additional budget for them too failed to obtain a majority. Huis Doorn plans to start a juridical procedure against the cuts. Also, the German Stiftung Preussischer Schlosser und Garten has indicated that they are quite willing to start talks with Huis Doorn on how they can help to keep the museum open.
On a side note, in December, over twenty silver objects, mostly cups, have been stolen from Museum Huis Doorn. Burglars gained access to the museum Sunday night, taking the items which represent a great cultural and historical value.
