Is Amsterdam below sea level ? Why is it not under water ?

Is Amsterdam in Netherlands really below sea level ?

If yes, why is it not under water ?

Yes, Amsterdam is about 2 meters (6.6 feet) below sea level. But the city is not under water, because of the sophisticated water management systems, that include network of canals, dikes, barriers, ditches and water pumps.

In the Netherlands, there are more places below the sea level than Amsterdam.

The part of Rotterdam is also below the sea level.
