The Royal House of Bourbon-Two Sicilies (pictured) - or Bourbon des Deux Siciles - is an ancient branch of the Spanish royal family which ruled parts of southern Italy for more than 100 years from 1734 to 1861. Its descendants still carry the name today, some 150 years later
On top of the presents, Carolina had a party more opulent than most weddings.
Taking guests to the Cervo Hotel at the Costa Smeralda Resort in Sardinia, where a double room cost £880 a night, Carolina partied the weekend away dipping in and out for the pool before getting dressed up for the evening celebrations.
A four-tiered cake, atop with sparklers, cherries and piped icing was served before a fireworks display, while guests danced with sparklers in front of a sign that read 'Happy Birthday Carolina', dozens of balloons and a tank of exotic fish.
Chiara shared more behind the scenes pictures of the night, including a lavish banquet of cheese, ham, grapes, olives and seafood.
Another snap showed Chiara surrounded by flowers and balloons as her parents held up two cakes for her.

Chiara and Carolina have become well-known in aristocratic circles for their lavish parties and fashionable looks at events.
Their father Prince Carlo holds a claim to the now defunct throne of the former House of Bourbon-Two Sicilies, a cadet branch of the Spanish royal family, which descends from the Capetian Dynasty and ruled over Southern Italy and Sicily during the 18th and 19th centuries.
Meanwhile, their mother, Duchess Camilla, born Crociani, is the daughter of Italian industry Tycoon Camillo Crociani and the actress Edy Vessel.
'We've known each other since we were little, my father Carlo is godfather to his younger sister,' she recently told Italian paper Corriere.
However, the rumours were squashed after the family didn't make an appearance at his father King Frederik's coronation.
While the Danish royal family never made a comment on the rumours, Chiara is not afraid to flex her connections.
'The Bourbon family is related to almost all the royal families or former rulers of Europe, it's a kind of big club,' she said.
Who are the ancient royal family of Bourbon-Two Sicilies?
The last King of Two Sicilies was Francis II, who was overthrown in 1860 and spent the remainder of his life in exile
The Royal House of Bourbon-Two Sicilies - or Bourbon des Deux Siciles - is an ancient branch of the Spanish royal family which ruled parts of southern Italy for more than 100 years from 1734 to 1861. Its descendants still carry the name today, some 150 years later.
The line descends from Philippe de Bourbon, Duke of Anjou, grandson of Louis XIV of France (1638–1715), who established the Bourbon dynasty in Spain in 1700 as Philip V (1683–1746).
In 1759 King Philip's younger grandson was granted the kingdoms of Naples and Sicily, becoming Ferdinand IV and III (1751–1825), respectively, of those realms. His descendants occupied the joint throne (renamed 'Kingdom of the Two Sicilies' in 1816) until 1860.
The family, then led by Francis II, was overthrown in 1860 by Italian general Giuseppe Garibaldi, who proclaimed a dictatorship on behalf of Victor Emmanuel II, the the King of Piedmont-Sardinia and later King of Italy. The Kingdom of the Two Sicilies and the Kingdom of Sardinia were merged into the newly formed Kingdom of Italy.
The deposed Francis II and his wife spent time in Rome as guests of the Pope where they ran a government in exile. They left the city before it was occupied by the Italians in 1870.
They led a wandering life from then on, living in Austria, France, and Bavaria.
Francis II died in 1894 and was succeeded by his half-brother, Prince Alfonso, who was in turn succeeded by his son, Prince Ferdinand Pius, Duke of Calabria.

The succession has been disputed since Ferdinand's death in 1960. Both his nephew Infante Alfonso, Duke of Calabria, and brother Prince Ranieri, pictured, laid claim to the throne. This feud continues between their descendants today
The succession has been disputed since Ferdinand's death in 1960 because he had six daughters and no sons to carry the family line.
Both his nephew Infante Alfonso, Duke of Calabria, and brother Prince Ranieri, Duke of Castro, laid claim to the throne. This feud continues between their descendants today.
Chiara and Carolina are the daughters of Prince Carlo, Duke of Castro, grandson of Prince Ranieri. The claimant on the other side of the family is Prince Pedro, Duke of Calabria, grandson of Infante Alfonso.

Prince Carlo, who only has two daughters, has overturned centuries of male primogeniture and has stated his title will pass to his eldest daughter, Carolina.
Prince Carlo married his wife Camilla, daughter of Italian film star Edoarda Crociani, better known as Edy Vessel, in 1998 at Monte Carlo cathedral. Camilla's sister Cristina revealed their mother was obsessed with her daughters marrying princes.
As Head of the House of Bourbon-Two Sicilies, Carlo holds many honours, including Sovereign Knight Grand Cross with Collar of the Order of Saint Januarius, of the Two Sicilian Sacred Military Constantinian Order of Saint George and Order of Saint Ferdinand and Merit.
Today Carlo and Camilla are 'very active in promoting the cultural, artistic, historical, and spiritual identity of southern Italy,' according to their official website. They split their time between homes in Monte Carlo and Paris.
Camilla is also active in charity work and gives her time to the Red Cross and UNICEF, as well as the Association Monaco Against Autism, Amitié sans Frontières et la Princess Grace of Monaco Foundation.
She campaigns against animal cruelty and is in charge of her own non-profit organisation, the Camilla of Bourbon Charitable Foundation, which works with the government in Mauritius to preserve its wildlife and promote sustainable development.

'King Felipe VI of Spain, he is my father's cousin and I am very close to the heir, Leonor, who, like me, loves sports and in particular women's football.
'Then the Belgian royals were often our guests in the summer in Saint-Tropez… and one of my best friends is Alexandra of Hanover, Caroline of Monaco's youngest daughter.'
While the family has no official remit, they spend their time doing charity work and promoting the interest of Southern Italy.
And the two sisters are also actively involved with charity work and rub shoulders with the most elite socialites of Europe, speaking fluently in English, French and Italian.
In recent years, they have been building a large fanbase by sharing snaps of their luxurious lives on Instagram, and clips of themselves on TikTok, dancing, showing off their style, and having fun in various glamorous locations.

In a snippet of the show shared on Instagram, Princess Carolina appeared to take a humble approach while shopping for sandals at a French market. 'I'm not interested in the brand,' she said.
During the clip, the sisters are seen enjoying the culture, restaurants and stunning views that the French town has to offer.
Chiara later shared a picture of her and Carolina in alike patterned boho-chic blue dresses alongside the writing: 'I hope you like it'.
The streaming platform explained: 'The Côte d'Azur fascinates the most fortunate, like princesses Carolina and Chiara de Bourbon des Deux-Sicilies or Pierre-Jean Chalençon.'
