Fonthill Abbey

In 1795, with a million pounds and nothing to do, William Beckford decided to build a Gothic cathedral on his estate. He skimped on materials, so the tower collapsed twice, but by 1813 it was finished, complete with front doors 35 feet high.

Beckford doesn’t seem to have known what to do with it. He used only one bedroom and dined alone, sending away the extra food. A new kitchen collapsed after Christmas dinner.

He finally sold it in 1822, and the tower collapsed for the last time in 1825. Today only a gatehouse remains.
