Copenhagen’s Black Diamond blends a centuries‑old national library with bold harbourfront architecture, quiet reading rooms, exhibitions, concerts and a hidden garden oasis.

Getting There
-
Metro and walking from central Copenhagen
From central Copenhagen, take metro line M1 or M2 to Christianshavn station, then walk around 10–15 minutes through the historic centre to the Royal Library on Slotsholmen. Metro trains run every few minutes throughout the day and a single adult ticket within the city zones typically costs around 20–30 DKK. The walk is flat and paved but can be busy in peak hours, and winter weather may make conditions colder and windier along the harbour.
-
Bus from inner city areas
Several city bus routes run to stops near Christiansborg Palace and the National Museum, from where it is about 10–15 minutes’ walk to the library complex. Typical bus journeys from inner neighbourhoods take 10–25 minutes depending on traffic, using the same ticket system as the metro with fares usually around 20–30 DKK for short city trips. Buses are frequent during the day but run less often late at night and on weekends.
-
Bicycle from across Copenhagen
Copenhagen’s extensive cycle lanes make it straightforward to reach the Royal Library by bike from most central districts in about 10–20 minutes. You can use city bikes or rentals, which usually cost from roughly 20–40 DKK per half hour depending on provider. Cycle parking is available around the library but can fill up at study rush hours, and strong harbour winds or wet weather may make the ride more challenging.
-
Taxi from the wider city
Taxis from central hotels or Copenhagen Central Station typically reach the Royal Library in 5–15 minutes, depending on traffic. Fares within the central area commonly range from about 80–200 DKK. Taxis can drop passengers close to the main entrance, which is useful for those with limited mobility, but costs are higher at busy times and during evenings or weekends.

Where Denmark’s memory meets the harbour
The Royal Danish Library on Slotsholmen is the country’s national library and one of Scandinavia’s most important cultural institutions. Founded in the 17th century as the king’s private collection, it has grown into the principal repository of Denmark’s printed heritage, maps, manuscripts, music and photographs. Today, more than a thousand people a day pass through its doors, from focused students and researchers to curious travelers seeking a glimpse behind the scenes of Danish culture. Set right on the edge of Copenhagen Harbour, the complex bridges city and water. The historic 1906 library building faces inward to the old town, while the waterfront side presents a dramatically different face: the jet‑black, faceted volume that has given the site its nickname, the Black Diamond. Between them, a soaring atrium stitches old and new together.The Black Diamond’s striking architecture
Completed in 1999, the Black Diamond is a landmark of contemporary Danish architecture. Its dark granite cladding and slightly tilted, angular form catch and mirror the sea and sky, constantly changing with the light and weather. Step inside and you emerge into a huge, light‑filled atrium carved through the building, where sweeping walkways, glass balustrades and curving balconies rise around you. From the upper levels, broad windows frame views across the harbour and into the city, while bridges lead back into the older library wings. Overhead, a monumental painting by Danish artist Per Kirkeby spans part of the ceiling, bringing bold colour and texture into the minimalist interior. The design feels both monumental and surprisingly calm, inviting you to linger rather than rush.Collections, treasures and quiet reading rooms
Beyond the public atrium, the Royal Danish Library shelters millions of books and an extraordinary range of special collections. As Denmark’s legal deposit library, it preserves every work published in the country, alongside important foreign works about Denmark. Manuscript collections include medieval codices, royal archives and papers from major Danish figures such as Søren Kierkegaard and Hans Christian Andersen, held in carefully controlled conditions. For visitors, glimpses of these riches appear in changing exhibitions that draw on the library’s treasures: illuminated manuscripts, rare early prints, historical maps, photographs and letters. Several reading rooms, from the more informal student spaces to the atmospheric Old Reading Room in the historic wing, give a sense of the library’s scholarly life, even if you are only here for a short pause.A cultural hub: exhibitions, concerts and photography
The Black Diamond functions as much as a cultural centre as a library. On the lower levels you find a café with harbour views, a small but well‑curated bookshop and flexible exhibition halls. The Dronningesalen, a 600‑seat concert and theatre hall, brings music, lectures and literary events into the building, turning the library into an evening venue as well as a daytime study space. Within the same complex sits the National Museum of Photography, whose collections trace the story of Danish and international photography from the 19th century onwards. Although much of the archive is tucked away, rotating displays highlight different themes and photographers, adding a visual counterpart to the written collections upstairs.Harbour views and the hidden library garden
Part of the appeal of the Royal Library lies outside its walls. On the harbour side, a promenade runs along the water, perfect for watching boats slide past the glass façade or for taking in the building’s reflections at different times of day. The mirrored exterior makes it a favourite spot for photographers, especially when the low northern light glances off the stone. Behind the complex, almost hidden from the surrounding streets, lies the Royal Library Garden. Enclosed by the old library and neighbouring historic buildings, this compact green space offers lawns, flowerbeds, trees and a central fountain. It is one of central Copenhagen’s quietest corners: a place to sit with a book, let children roam safely, or simply enjoy a pause between nearby sights such as Christiansborg Palace and the National Museum.Iconic landmarks you can’t miss
