Something significant happened in Tandil, Argentina, on Feb. 29, 1912 — a 300-ton stone that had perched impossibly on the edge of a local hill suddenly tumbled to the bottom and broke into pieces.

Whether this happened due to vandalism or to blasting at a local quarry is unknown — there were no witnesses.

In 2007 the town replaced it with an exact replica. To date, it’s still there.

Stranded in Java after the Japanese invasion of 1941, the Dutch minesweeper Abraham Crijnssen found a unique way to sneak out: The crew covered the decks with jungle foliage and painted the hull to resemble cliffs, giving the ship the appearance of a small island.

Traveling only at night and anchoring near shore, the minesweeper gradually made her way to West Australia, becoming the last Allied vessel to escape Java and the only one of her class in the region to survive.

Germany’s Heidelberg Castle is home to a famously enormous wine barrel, capable of holding 57,853 U.S. gallons. This is actually the most recent of four enormous wine barrels that the castle has housed, the first built in 1591. Unfortunately it’s empty — today it serves mostly as a tourist attraction and a foundation for the fanciful dance floor above it.

“Everybody has heard of the great Heidelberg Tun,” wrote Mark Twain in A Tramp Abroad, “and most people have seen it, no doubt. It is a wine-cask as big as a cottage, and some traditions say it holds eighteen thousand bottles, and other traditions say it holds eighteen hundred million barrels. I think it likely that one of these statements is a mistake, and the other is a lie. However, the mere matter of capacity is a thing of no sort of consequence, since the cask is empty, and indeed has always been empty, history says. An empty cask the size of a cathedral could excite but little emotion in me.”
