More About Helsingor, Denmark(Wikipedia)
Helsingør [hɛlseˈŋøɔ̯ˀ], also known by its English name Elsinore, is a city in Helsingør municipality on the northeast coast of the island of Zealand (Sjælland) in eastern Denmark. 

It is known internationally as the setting of William Shakespeare’s Hamlet. The name is derived from *Hals meaning “narrow strait” and it referred to the narrow passage between what is now Elsinore and Helsingborg.

Prior to the Middle Ages it was just a marketplace where people sold goods, including women. About 1200 AD the first church, Sct Olai Church, was built. A number of convents once surrounded the church, but now all that remains is the church building, today the cathedral of the Diocese of Elsinore.
