Kronborg Castle
Kronborg Castle is a big stone castle by the sea in Denmark. Long ago, every passing ship had to pay money here!
Kronborg Castle stands at Helsingør, in Denmark, where the strait between Denmark and Sweden is only 4 kilometers wide. King Frederik II built it from 1574 to 1585, and ships passing by paid a toll here for centuries. It is also known as Elsinore, the castle in Shakespeare's play Hamlet.
Kronborg Castle, north of Helsingør (Elsinore) at the narrowest point of the Øresund, is a Renaissance castle begun by King Frederik II in 1574 on the site of the 1420s fortress of Krogen. Rebuilt almost exactly as before after a fire in 1629 and ringed by later ramparts and bastions, it was where Denmark collected the Sound toll until 1857. It was inscribed on the World Heritage List in 2000.

Discover Kronborg Castle
Kronborg Castle is in Denmark. It stands by the sea, right where Denmark and Sweden are very close together.
It is made of pale stone, with tall towers and copper roofs.
Kronborg Castle stands just north of the town of Helsingør, which is also called Elsinore. It sits beside the Øresund, the narrow stretch of sea between Denmark and Sweden. Here the water is only about 4 kilometers wide.
The Øresund is a gateway to the Baltic Sea, so ships going in or out sailed right past the castle. UNESCO added Kronborg to the World Heritage List in 2000.
UNESCO places Kronborg north of Elsinore on a strategically important site commanding the Sound (Øresund), which is only four kilometers wide at this point and is the gateway to the Baltic Sea. From the 16th to the 18th centuries, it says, the castle played a key role in the history of northern Europe.
Kronborg was inscribed in 2000 under criterion (iv), as an outstanding example of the Renaissance castle. UNESCO notes that the castle's overall impression is closely tied to its architecture and location, which together stress its symbolic, commercial and strategic importance.

A castle that collected tolls
Long ago, ships sailing past the castle had to stop and pay money, called a toll.
The king used the money to build a grand new castle here.
In the 1420s, Eric of Pomerania built a first fortress here, called Krogen. From 1429 until 1857, Denmark made the ships sailing through the Øresund pay a toll at the castle. UNESCO counts about 1.8 million ships in that time.
In 1574, King Frederik II began a new castle in place of Krogen, and it was built by 1585. The castle's managers say the toll money paid for the castle and other royal projects.
UNESCO dates the first castle, Krogen, built by Eric of Pomerania, to the 1420s; remnants of its walls can still be seen. From 1429 to 1857 Denmark controlled the passage and collected the Sound toll at Kronborg, from around 1.8 million ships. The toll was also a political tool: by favoring the shipping of chosen nations, Denmark could build alliances.
The castle's own history says Frederik II built Kronborg between 1574 and 1585, as both a strong fortress and a home for the growing royal family, and that the toll revenues went into the king's treasury and helped pay for the castle.
White stone and golden spires
The castle has four wings built around a big open courtyard.
Its walls are covered in pale sandstone, and its towers have pointed tops.
Kronborg has four wings around a large courtyard. Halfway through building it, Frederik II changed his plans: the red brick walls were covered with costly white sandstone, and the castle got copper roofs and gilded spires.
In 1629 a fire destroyed most of the inside. King Christian IV had the castle rebuilt almost exactly as it had been before.
UNESCO describes a Renaissance building of four wings around a spacious courtyard, with bright sandstone facades marked by horizontal bands, towers and spires, and rich sandstone ornament. The castle's history adds that midway through construction Frederik II had the red brick walls faced with costly white sandstone from Scania and Gotland, under copper roofs and gilded spires.
After the fire of 1629 the castle was rebuilt shortly afterward in almost precisely the same shape; UNESCO notes that the chapel was the only part not damaged. Its Great Hall, or banqueting hall, is in UNESCO's words the largest of its kind in northern Europe.
Castle and fortress
Around the castle are thick earth walls covered in grass. They made the castle a strong fortress.
Kronborg is also famous from a play by William Shakespeare called Hamlet.
UNESCO says Kronborg was admired for its beauty as a castle and feared for its strength as a fortress. Tall earth ramparts and pointed bastions surround it, and its defenses were made stronger in the late 1600s.
Kronborg is also known around the world as Elsinore, the castle where William Shakespeare set his play Hamlet.
UNESCO notes that the castle was protected by tall ramparts and strong angular bastions, and that its defenses were reinforced in the late 17th century according to the military architecture of the period. The castle has undergone several alterations over the centuries, but UNESCO says it has remained intact.
Kronborg is world-famous as the setting of Shakespeare's Hamlet. The castle's own history says it is told that Shakespeare drew on stories of life at the Danish court, carried by actors who had performed at Kronborg for Frederik II and Queen Sophie.
