While the location of Arendelle is never specified in the film, the name of Arendelle (named after Arendal, a small town located south-west of the Norwegian capital, Oslo) hints that the kingdom may be somewhere far north, like Norway or Denmark on the coast.
From the fashion of the upper and lowerclass, the architecture, culture and written language show nordic/french-germanic influence in a 16th-17th century setting.
Due to the unstable nature of Elsa's powers, for her safety as well as the safety of Anna, until Elsa can learn to control her winter magic, the castle was closed off on the late king's orders for 13 years. On the day of Elsa's coronation, when her magical abilities were unintentionally exposed to the public by Anna and runs away, she accidentally triggers the severe winter weather conditions that freeze the kingdom. While she is gone and Anna is searching for her, Hans takes on the task of protecting the kingdom. However, thanks to Anna's efforts and love for her sister, Elsa found the courage to undo the eternal winter and peace is restored, along with Hans being sent back to face punishment from his brothers for his actions against the princess and queen.
Home of the royal family of Arendelle. The east side of the castle is where the main gates are located below a clock and in between two smaller doors, one on each side, all connected to Arendelle via a bridge. The doors to the castle are directly across from these gates and to the left and right of the gates are towers. The only tower on the right and the immediate one on the left are equidistant from the gates, identical and bear a shield with Arendelle's crest. Along the wall between the gates and these two towers are shields of various design and color, each unique. There is a slightly taller tower further left at the end of the east wall, and across from the first left tower is the front end of the chapel where Elsa is crowned. The north side of Arendelle's castle is the most fortified with four towers, each of differing shape, height and width, and a thick, portruding and high stone wall. On the furthest right is the tallest and widest tower to the left of that is a shorter, square-shaped tower and between the two is the fortified, portruding wall. To the left of this tower seems to be a part of the castle based on the similar design of a spire and the roof. Across from the back side of the chapel is a heavier, square-shaped tower, wider and shorter than the other. And to the left of that is the end of the north wall and a more familiar though shorter tower with a similar circle shape and cyndrical roof design as the towers on the east side of the castle. The south side is connected to the lighthouse which is one of the two structures marking the opening in which ships must pass through to enter into Arendelle.
Where Elsa is crowned as the new queen of Arendelle. In the chapel, the Bishop of Arendelle places the crown on Elsa's head as Anna watches the coronation. He then presents the scepter and orb on a pillow. As Elsa moves to pick them up, the bishop reminds her that she has to remove the gloves she always wears. Elsa then faces the people in the pews and he formally speaks in Old Norse, ordaining Elsa as Queen. He barely finishes before Elsa hastily replaces the scepter and orb, shoving on the gloves. She turns again towards the people who are standing and applauding in honor of the new Queen.
Freely and expressing her feelings with her ice powers, Elsa creates her ice castle after her self imposed exile. It is under the protection of the ice golem Marshmallow.
Wandering Oaken's Trading Post and SaunaEdit
The trading post is a little log cabin located in the mountains, that is owned by Oaken. There are two signs that say "Wandering Oaken's Trading Post" and "And Sauna." It is the place where Anna goes to get winter clothing and meets Kristoff.
Valley of the Living RocksEdit
A small valley home of the trolls, Kristoff's adoptive family.
Role in the CrossoverEdit
Being the home of Elsa and Anna, Arendelle is to be expected when they are involved. In Frozen Tangled Guardians, Arendelle could be interchangable with Corona as Rapunzel's kingdom. Arendelle would be allied with other kingdoms in the fandom, including Berk, DunBroch, and Corona.
It could be possible that Corona and Arendelle may be associated with each other in-canon. Rapunzel and Eugene both make a cameo appearance in Frozen before the coronation. This is probably because the creators of Tangled (2010) were also in charge of creating Frozen along with the creators of Wreck-It-Ralph.
