Construction on the US White House began in 1792. It has been almost continuously occupied by US presidents since 1800, barring a few years after the British set it on fire in 1814.
But that doesn’t mean that the present-day building is free of hazards—there are mice, cockroaches, and ants. And as of this past weekend, a sinkhole has been growing on the north lawn, Voice of America reporter Steve Herman observed, just near the press briefing room.
“This week I’ve been observing a sinkhole on the @WhiteHouse North Lawn, just outside the press briefing room, growing larger by the day,” he tweeted.
“It was noticeably bigger between Sunday and Monday,” Herman said. “It’s more than a foot long right now,” he said. A second sinkhole has opened up right next to it, he said.
Often described as a “swamp” of corruption, parts of the city of Washington, DC, are also literally built on a swamp. The city’s geological issues also include “forebulge collapse,” a post-Ice Age condition that means the city could sink as much as six inches this century.
