Frederiksborg Castle closes three rooms from 23 October

Frederiksborg Castle will close three interior spaces from 23 October 2026 while the Museum of National History prepares its Christmas installation and exhibition. The change affects visitors to the Rotunda, Løngangen and the Audience Chamber at the Danish castle in Hillerød, while the museum itself remains open.

The castle is also known locally as Frederiksborg Slot, a name visitors may see on Danish signs and official information.

Christmas preparations close three castle rooms

The museum’s latest visitor update says the Rotunda, Løngangen and the Audience Chamber will be closed from 23 October through 30 October 2026. The same update states that Valdemarsalen will be open for passage only from 19 October to 30 October because of preparations for the Christmas installation and exhibition.

The restrictions are temporary and concern named rooms rather than the whole attraction. The museum says it is open every day, and its programme continues to list exhibitions including Icy Christmas - Hans Christian Andersen & The Snow Queen from 31 October 2026 to 3 January 2027, alongside Medieval Modern - Agnes & Harald Slott-Møller.

The dates and affected spaces are set out in the museum’s visitor update. For travellers arriving between 23 October and 30 October, the practical result is a partial route through the interior, not a full closure of the castle museum.

Frederiksborg Castle links the change to its museum history

The building stands on three small islets in Castle Lake in Hillerød. King Christian IV built the Renaissance complex between 1600 and 1620, making it the largest Renaissance complex in the Nordic region, according to the museum.

Frederiksborg Castle has housed the Museum of National History since 1878. The museum presents 500 years of Danish history through portraits, history paintings, furniture and applied art, so a temporary room restriction changes the route through a collection spread across a substantial royal complex.

The Audience Chamber has particular historical significance within that story. It survived the major fire of 1859, which destroyed large parts of the interior, while the Chapel also remained virtually unscathed. The museum’s account of the building’s history explains why a temporary closure of one named room is different from the loss of access to the whole site.

The setting also connects the rooms to the wider complex: the castle gardens include both a Baroque garden and an English-style garden, with the small Bath House Castle in the latter. These outdoor areas are separate from the three rooms listed in the closure notice. Further background appears on the museum’s castle history page.

Christmas exhibition follows the late October restriction

The partial closure precedes the public start of Icy Christmas - Hans Christian Andersen & The Snow Queen on 31 October 2026. The exhibition is presented in cooperation with The Royal Danish Theatre, while the museum separately lists Medieval Modern - Agnes & Harald Slott-Møller from 8 October 2026.

This sequence gives the access change a clear place in the autumn programme. Visitors during the final week of October should expect the installation work to shape the interior route, while visitors from 31 October can find the Christmas exhibition listed as a current museum event.
