Corona

Corona  is the name of the Kingdom in the Disney film Tangled  where Rapunzel  was born and later reunites with her  family.

Location
The location of Corona is never actually given, but from the characteristics of the kingdom, it is presumed to take place somewhere in Western Europe.

Characteristics
From the appearence of the architecture, fashion, ethnic populous, etc, it can be assumed that Corona can be found somewhere in Western Europe, possibly of French-Germanic origins.

The Castle
The home of The King and Queen and their daughter Rapunzel and later Flynn Rider.

The Village
The area where the actual residents live in Corona. The city surrounds the castle on the island.

The Market
The area where Rapunzel and Flynn explore and dance.

The Sea
The Baltic Sea coast is overwhelmingly flat. There are no places that match the hills that Flynn runs into with the stolen crown, or the steep-walled valley that hides Rapunzel's tower. But one region at least comes close.

The Prison
The Prison where Flynn was held until he was to be hung. Flynn remained here until 5 Pub Thugs and Maximus help him escape.

The Chapel
The Chapel is the place where Rapunzel and Eugene got married, or in the crossover's case, any marriage that the characters go through, whether it's with Rapunzel and Jack, Merida and Hiccup (as guests to the kingdom) or any variation between them.

The Snuggly Duckling
The Snuggly Duckling is the pub where the Pub Thugs hang out in the movie Tangled. Despite having what seems to be a "cute" name, the Snuggly Duckling is definitely not a cute place. Rapunzel discovers this when she and Flynn walk in and she sees the Pub Thugs.

Role in the Crossover
Since Corona is Rapunzel's birthplace (and birth-right) stories involving Rapunzel would inevitably lead too or come from Corona. Corona would be allied with other kingdoms in the fandom, including Berk, DunBroch, and even Arendelle.

It could be possible that Corona and Arendelle may be associated with each other in-canon. Rapunzel and Eugene both actually makes an 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.
