Slovakia

A relatively small part of the country's area is covered by lowland areas - about 40%.

An excerpt from the article 37 facts about Slovakia

These are three lowlands: the Záhorská Lowland - the smallest, in the southwestern part of the country, the Danubian Lowland - the largest, and the Eastern Slovak Lowland - in the south and southeast, with the lowest point of the state's surface (94.7 m above sea level) at the intersection of the Bodrog River with the state border.
