Yesterday I took a long train ride to the South to visit relatives.
On my way back I walked through the village of Baarlo. One of its four (!) castles is Castle d’Erp which was for sale in 1972 for 1 guilder. I know this because at the time, my parents were considering buying it. While the (obviously symbolic) price was low, the snag was that necessary roof repairs were estimated to cost over a million guilders (somewhere between 250,000 and 500,000 US dollar at the time, I guess). Since my parents did not have that kind of cash lying around, they tried to move other families to buy it with them, a scheme that ultimately failed. The castle was then bought by the municipality.
