Back in 1502 on the 21st of May, an island was discovered off the coast of Africa. It was named Santa Helena, after the saint Helena of Constantinople.
Since 1945, the people of St Helena have celebrated their national day on 21st May.
The Falkland Islands have close ties with St Helena, and at the last census, 10% of the population was made up of people born in St Helena.
We spoke to two locals about growing up there and how they celebrate this special day.
