The Vessels at Holmen are included on the Discover card, not Hop. Three Cold War naval exhibits sit together: a frigate, a submarine and the 1749 mast crane.
One scan on the Discover card covers three exhibits moored together. It publishes no admission price, which is worth saying before the rest.
Three exhibits moored and standing together on the old naval base: a frigate, a submarine and a crane from 1749. Allow an hour and a half.
A small diesel-electric boat with eight torpedo tubes, built to land naval special forces — and the only Danish submarine ever to take part in hostilities. It served in NATO counter-terrorism operations in the Mediterranean in 2002, then was diverted to the Arabian Gulf alongside the corvette Olfert Fischer during the second Iraq war. Decommissioned in 2004.
Visitors go through the crew quarters, which is the part that stays with people. The history explains what the boat was for; the living space explains what it was like, and no amount of reading does that job as directly as standing in it.
Peder Skram is a Cold War frigate you board and walk. The Mast Crane, the most significant building on Holmen, has been standing since 1749 — it stepped masts into ships when that was the hardest job on the base. Three eras of the same naval yard, side by side.
Two things about the visit itself that outrank the history, and two the sources do not settle. Confirmed against peder-skram.dk.
Holmen is the old naval base across the harbour, about 20 minutes out on bus 2A. The journey is on the Discover card, and only on that one.
All three are included on the same card, so the only cost of adding them is the time. For the full list, see every attraction the Copenhagen Card covers.
Large-scale installation art in the former welding halls on Refshaleøen, with room for work most galleries cannot hang.
The baroque church in Christianshavn with the external spiral staircase winding up the outside of its spire.
The Royal Library extension in black granite on the waterfront, with exhibitions and a reading room over the harbour.
The Discover card includes all three exhibits and the bus out to Holmen, along with 80+ more attractions and unlimited public transport across the Capital Region.
The Copenhagen Card Discover covers all three exhibits on one scan — the frigate Peder Skram, the submarine Sælen and the Mast Crane of 1749 — plus the bus out. They do not publish an admission price, so this page states no figure. The Hop card covers none of it.
Neither the Monday rule nor the season is published anywhere we can check, so this page claims neither. Sites that are afloat often run seasonal hours, so check peder-skram.dk before you travel rather than assuming — this is the venue on the card where an unchecked trip is most likely to be wasted.
Nothing needs booking. Show the QR code in the Copenhagen Card app at the gangway and go aboard. Getting below decks means ladders and hatches, so this is worth thinking about in advance if anyone in the group would find that difficult.
One scan per attraction applies, and all three vessels count as that one attraction rather than three — so the single scan gets you the frigate, the submarine and the crane. Most people spend about an hour and a half over the lot.
Show the live QR code in the Copenhagen Card app at the entrance and let staff scan it. Your booking confirmation email is not your card, and a screenshot of the QR code will not scan — it has to be the app itself, which works offline once activated.
