Rosenborg Castle (Rosenborg Slot) is a Dutch Renaissance palace built between 1606 and 1634 by Christian IV as a summer retreat, set inside the King's Garden (Kongens Have) in central Copenhagen. Its basement Treasury holds the Danish Crown Jewels and coronation regalia - treasures still used by the reigning monarch - alongside 400 years of royal collections, making it one of the city's best indoor sights. In 2026 it remains open as a museum run by the Royal Danish Collection, with timed-entry tickets that often sell out in peak season. Pair a visit with a stroll through the surrounding garden for an easy half-day.
The basement Treasury (Skatkammeret): the Danish Crown Jewels and royal crowns, comprising diamond, ruby, pearl and emerald garnitures - among the rare regalia in the world that are both on public display and still worn by royalty.
The top-floor Long Hall / Knights' Hall (Riddersalen): a roughly 40-metre hall with Christian V's silver coronation throne on narwhal-tusk legs, guarded by three life-size silver lions, plus a rare set of 17th-century silver furniture.
Christian IV's private rooms, including his Writing Closet, a Dutch-tiled bathroom and the Winter Room hung with Flemish paintings.
Lavish royal craftsmanship such as the Venetian glass cabinet and Flora Danica porcelain.
The King's Garden (Kongens Have) that surrounds the castle - Denmark's oldest royal garden, free to enter, with rose beds, a Hans Christian Andersen statue and the changing of the Royal Life Guard passing nearby.
Good to know
RulesAdmission uses timed slots every ten minutes and often sells out on the day in high season. Book online at the official site (denkongeligesamling.dk) to secure your slot and skip the ticket-window queue. Under-18s enter free but still need to hold a (free) ticket.
SeasonIn July Copenhagen stays light until around 10 pm, so you can sightsee late, but showers are frequent (rain on roughly 13 days a month) and temperatures swing - pack a light layer and a waterproof jacket. The interior is a good rainy-day option; the garden is nicest on a clear morning.
SafetyNørreport station right beside the castle, along with the Strøget shopping street and Nyhavn, are known pickpocket spots. Wear a zipped cross-body bag at the front and keep your phone and a card in an inside pocket rather than a back pocket.
CautionBuy tickets only from the official website and avoid marked-up resellers. Denmark is nearly cashless, so a contactless card is easiest - but if a card terminal offers to charge in your home currency, decline and pay in Danish kroner (DKK) to avoid poor dynamic-conversion rates.
MannersTipping is not expected in Denmark; service is included and rounding up for exceptional service is plenty. The Treasury is small and can get crowded, so keep quiet and follow the photography rules (no tripods or flash).
RulesThe Treasury is in the basement and the thrones are on the top floor, with narrow spiral staircases in between, so large suitcases, big backpacks and strollers may be restricted. Leave heavy luggage at your accommodation or a station locker and travel light.

Adult tickets are around 140 DKK, students about 90 DKK, under-18s free, and the Copenhagen Card is accepted - but prices and hours change, so always confirm the latest details on the official site before you go.
