strong walls
so why?
the food they eat makes them strong
The Eiffel is very stable because Gustave Alexandre Eiffel who built it used many well thought out structural members to support the body and shape of the iron tower!!!
the shell shape makes it strong.
The Clock on Parliament Hill, is called the Peace Tower. The Peace Tower, so named to honour the thousands of Canadian men and women who sacrificed their lives for their country in World War I, stands at the front of the Centre Block.
The supports that are under the bridge is very thick and strong which makes londen bridge strong.
I'm glad you asked. i did a project on the peace tower a few years ago and have some interesting facts. 1. because of the 1950's style clock, the peace tower clock only goes forward, so at daylight savings time an employee stops the clock, waits an hour and starts it again. 2. you can acually buy a souvenir flag that flew on the peace tower. but you have to be patient! there is a 20 year waiting list! 3. the peace tower was built to replace the Victoria tower after the fire of 1916. the only part of the parliament buildings that survived that fire was the library. 4. there are 370 carvings and grotesques on the peace tower, of which only four are gargoyles. 5. the four gargoyles stick out from the peace tower's corners just below the clock, you can see them if you look closely in pictures, but it is hard to figure out what they are. they are in the shape of a woman, a lion, a dragon and an eagle. 6. the peace tower is made up of around 54,000 stones. 7. the stones of the peace tower are prehistoric and have fossils in them! you can see them from the inside only, though.

its the only one in the world
the Eiffel tower is made of long steel beams which allows it to withstand storms and such. the tower is more than five million pounds, which holds it to the ground. all of the different parts of the tower are attached together tightly, not sure what holds it together though. but it must be strong as diamonds to be so enormous and stable.
