The Warship Vasa Comes Back Up
In 1628, a grand new warship named Vasa was launched in Stockholm, Sweden. Crowds came to watch. The ship was covered in carved wooden figures and painted in bright colors. But Vasa sailed only a short way before a gust of wind tipped it over, and it sank in the harbor.
What went wrong? Experts have studied the ship and found that it was too narrow and too heavy near the top. It carried many cannons and tall decks, but it did not have enough weight low down to keep it steady. In those days, builders had no way to test such a ship before launching it.
Vasa then lay on the harbor floor for more than three hundred years. The cold Baltic Sea water has little salt, and the wood-eating worms that destroy ships in saltier seas do not do well there. Because of that, the wood stayed in good shape.
In 1961, divers and workers lifted the ship from the water with great care. Specialists treated the old wood so it would not crack as it dried. Today Vasa sits in a museum in Stockholm, where visitors can see a ship from nearly four hundred years ago.
