On our recent trip to Europe, we visited Lucca, Italy, a town in northern Italy west of Florence. Our guide told us about the inhabitants of the city during the 13th century and how to show their prestige they would build a tower next to their home. Each one built a little higher than the last person.
The city government finally said enough and enacted a building code for the maximum height of any tower. So, this owner decided that since the code didn't say anything about items on top of the built structure, they would create a 10-foot-deep pit at the top and fill it with dirt. Then they planted trees to make their tower look taller than anyone else's.
Good thing they don't have California sequoia trees in Italy.
