Colonnade of Apollo (1783) | Pavlovsk

There is some disagreement on whether this is an artificial ruin or not, but the most popular story is that it isn’t. A few years after being built, the colonnade was moved to a different spot in the park and a cascade was added. Maybe the water flowing down the cascade weakened the foundation. But after a terrible thunderstorm one night around 1817, residents of the palace awoke to find that part of the structure had collapsed. After awhile, it was decided that the colonnade looked even more poetic as a ruin, so it was left that way.
