polders
The European nation that has had much land reclaimed from the sea is the Netherlands. Much of the nation is below sea level and is protected by a vast system of dikes that hold the water back.
The Netherlands is known for its intricate system of canals and pumps that drain water and create polders, which are low-lying areas reclaimed from the sea. This engineering marvel allows the Dutch to live and farm below sea level.
The Netherlands is the European country known for having land below sea level. Approximately 26% of its territory lies below sea level, primarily in areas known as polders, which are reclaimed from the sea and protected by dikes. This unique geographical feature has led to advanced water management and engineering practices in the country.
I know that the dead sea is below sea level
Both have large areas that are flat and below sea level.
Former bodies of water like lakes where they reclaimed the land by pumping out the water. The entire province of Flevoland is a polder. It used to be a sea. The sea became a lake when they build a large dike called the afsluitdijk. Later they surrounded a large part of the water with dikes and pumped out the water thus creating land that is below sea level. Of the dutch landmass approx one third is below sea level.
Reclamation usually involves construction on areas that ere previously below sea level. Either the ground level is built up by the tipping of rockfill or berms are created and the water removed by pumping to create an area of dry land that is below sea level (this is a very common process in Holland). The problem with this is that the amplitude of seismic waves is related to the ground through which they travel. The amplitude of seismic waves in poorly compacted sediments (such as those likely to be found in reclaimed areas) tends to be larger than that which would occur where the founding material was stiffer and stronger (e.g. areas founded on bedrock). As such for a given earthquake, buildings in areas that are reclaimed are likely to experience more severe ground shaking than in other areas making them more likely to collapse. Further to this, sediments can undergo a process known as liquefaction where the pore water pressure is driven up to such a high level the individual soil grains effectively become buoyant and the soil loses it's ability to support surface loads which can also lead to buildings collapsing. Finally areas of reclaimed land that are still below sea level or are near the coast will inherently be at greater risk from a tsunami than other areas.

The Netherlands. Or Holland as many people call it. Holland is really a province in The Netherlands.
The countries that are predominantly below sea level are the Netherlands and Maldives. Parts of other countries like Bangladesh and some island nations are also below sea level in certain areas.
Switzerland and the Netherlands are both democratic countries in Europe and are both approximately the same size, after that the similarities end. The Netherlands is a coastal country, Switzerland is land-locked. The Netherlands is a very flat country, much of its land is below sea and reclaimed from the sea. Switzerland is mountainous, over 50% of the country is mountains, mostly the Alps. The Netherlands is monolingual (speaks Dutch), Switzerland has 4 official languages: German, French, Italian and Romansh. Different languages are spoken in different parts of the country. The Netherlands is a monarchy, Switzerland is a confederation and is a republic.
The Netherlands has the greatest percentage of land at an elevation below 200 meters altitude, with a significant portion of the country being below sea level. Other countries with large areas below 200 meters altitude include Bangladesh and some coastal regions in countries like Egypt and Vietnam.
The Netherlands, Belgium, and Luxembourg are the Low Countries. They are called so because they are mostly below sea level.
