Suriname is a country on the northeastern Atlantic coast of South America, which currently does not have its own location stamp.
At just under 165,000 square kilometers (64,000 square miles), it is the smallest sovereign state in South America.
It has a population of approximately 575,990 dominated by descendants from (slave) laborers brought in from Africa and Asia by the Dutch Empire and Republic. Most of the people live by the country's (north) coast, in and around its capital and largest city, Paramaribo.
The official language is (Surinamese) Dutch, while 8 more indigenous languages are recognised regionally. Sranan Tongo, English-based creole language, is also spoken by most people in Suriname as a lingua franca.
Suriname is dominated by tropical rainforests and
the Central Suriname Nature Reserve
is a conservation unit, which preserves one of its areas.
Duivels Ei (Devil's Egg)
is a famous natural monument in that reserve, a rock seemingly balanced on the edge of a mountain, which I believe would make a lovely stamp.
