Haraldsborg is a city built at the site of OTL Manhattan, named after Prince Harald of Denmark, official discoverer of Atlantis. In 1387, on his second journey, he came as far as to the island that was named Prince-Harald-Island in his honor and founded a settlement that would become Haraldsborg. When the Black Death hit Atlantis in 1435, the Danes had to give up most of their settlements, but Haraldsborg survived. 1438, when Denmark and the Netherlands divided the New World between them, Haraldsborg stayed Danish.
