AART Architects Win Bid for Subterranean Royal Treasury at Rosenborg Castle, Copenhagen
AART, a Danish architectural practice, in collaboration with VEGA Landskab, Fogh & Følner, and Artelia, has emerged victorious in an international competition to design the Rigets Skatkammer (The Royal Treasury), a significant subterranean expansion of the museum at Rosenborg Castle in Copenhagen. This ambitious project entails a 1,300-square-meter extension, including approximately 600 square meters of new exhibition space, meticulously planned to reside beneath the historic moat. The design also aims to partially restore the water feature surrounding Christian IV's Renaissance castle, enhancing its historical context.
The proposed design strategically leverages the historic moat as its foundational architectural concept. Water elements are key to re-establishing the castle's original connection to its island setting. Upon arrival, visitors will encounter two distinct pathways: one leading across a newly constructed bridge towards the main castle, and another guiding them along the moat's edge towards the underground museum entrance. The journey into the subterranean space is facilitated by a subtly designed opening in the ground, drawing visitors beneath the water's surface. This thoughtful transition aims to seamlessly connect the bustling urban environment above with the tranquil historical landscape and the invaluable treasures housed beneath.
The visitor's experience is further enriched by a carefully orchestrated sequence of changing spatial environments as they move from the open landscape into the enclosed exhibition areas. Variations in natural light, acoustic qualities, spatial dimensions, and material textures define this route. The architectural narrative progresses from brighter, more expansive areas towards the dimmer, more intimate setting of the treasury, guiding visitors through a captivating journey. The design ensures that both arrival and departure are integrated into a continuous narrative, allowing guests to re-engage with natural light and the historical surroundings as they conclude their visit. This thoughtful approach by AART aims to forge a profound connection between the daily life of the city above and the significant royal artifacts safeguarded below.
The underground exhibition spaces are envisioned as a tangible, mineral-rich environment, incorporating materials such as natural stone, concrete, and metal. This material palette not only echoes the existing character of Rosenborg Castle but also establishes a contemporary architectural language for the new museum. The ambient conditions within these subterranean areas are designed to subtly shift with external factors like weather, time of day, and the changing seasons, thereby reinforcing the inherent link between the modern museum extension and its historic landscape setting.
The project, initiated by the Danish Agency for Culture and Palaces, has received crucial funding from the A.P. Møller Foundation, Augustinus Foundation, and the Danish state. The competition saw several prominent architectural firms shortlisted alongside AART, including BIG – Bjarke Ingels Group with Over Byen Arkitekter, OPLAND, WSP, Steve Webb, and Jensen Hughes; Dorte Mandrup Arkitekter with Marianne Levinsen Landskab, H+, and Søren Jensen; Henning Larsen with Erik Brandt Dam arkitekter, Elgaard Architecture, Rambøll Danmark, and VITA Ingeniører; and Lundgaard & Tranberg Arkitekter with LYTT Architecture, SWECO, Rønnow Arkitekter, and Ad Usum by Hans Scheving. AART's winning design represents a harmonious blend of historical reverence and contemporary architectural vision, promising a unique cultural experience for future visitors.
