HELSINGØR HELSINGØR, Denmark, a historical town at the northeastern tip of the island of Sjælland, 50 km north of Copenhagen. It is in a farming region on the west side of the 4 km wide Øresund separating Denmark from Sweden. Helsingør grew up around a Carmelite monastery, built under the auspices of Eric of Pomerania in 1430, and Kronborg Castle, built by Frederik II between 1574 and 1585. This castle, which was used to enforce the toll assessed on ships passing through the sound, was the Elsinore of Shakespeare's Hamlet. The toll, collected from 1425 until 1857, was abandoned, after the refusal of the United States to pay it, for a sum of USD 16 million, paid by the interested parties. Helsingør is the terminus of a rail and auto ferry connecting Denmark with Hälsingborg, Sweden; this line is the main railway link between Sweden and southern Europe. The International Peoples's College is located in Helsingør. The main industries are shipbuilding, commercial distribution, and transportation. Pop. (est. 1990), 56.700.
