Copenhagen's must-see sights are compact enough to walk between and old enough to argue about. The range runs from a palace that is the seat of the Danish Parliament and a palace that is still home to the Danish royal family to a bronze statue from 1913 and a road and railway bridge over the Øresund. Churches carry much of the list, among them the National Cathedral of Denmark, a Catholic cathedral on Bredgade, and a church on På Bjerget that dates from 1940. The dates matter here: Rosenborg Castle dates from 1606, and the Copenhagen Opera House dates from 2005. This list is for visitors who want the city's main sights without filler and who are willing to plan around opening hours. The hours change from place to place and from day to day, so each entry gives them wherever they are known. Read the entries before you build the day, not after.

1 The Little Mermaid
A 1913 bronze statue by Edvard Eriksen
On a clear morning, the 1913 bronze of The Little Mermaid catches the light, and that small figure is the whole event. The sculptor was Edvard Eriksen, and his statue works best when you look at it slowly, not when you shoot it over someone's shoulder. Skip the midday coach rush and come early or late, when you can stand still in front of it for a few quiet minutes. Treat it as one stop on a longer walk, not as a destination in itself. Look at how the bronze has been handled, take your picture and move on. The statue dates from 1913, and it repays close attention more than it repays a long journey made solely to see it.

2 Øresund Bridge
A road and railway bridge over the Øresund
Dating from 1999, the Øresund Bridge carries both road and railway traffic across the Øresund, and that double purpose is the reason to come. Don't bother treating it as a photo stop: you experience this structure by crossing it, so take a seat on the train or in a car and watch the water open out beneath you. It earns its place among the palaces and churches for a different reason. They show how the region remembers, and this bridge shows how it moves. As a piece of 1999 engineering, it is the newest kind of landmark there is, one that people use every day without thinking about it. Go once on purpose and pay attention.

3 Christiansborg Palace
A palace that is the seat of the Danish Parliament
Christiansborg Palace is the seat of the Danish Parliament in Copenhagen and dates from 1740, so the country's present-day business goes on in rooms that carry that past. We'd skip the impulse to treat it as one more royal interior to tick off. What makes it worth your time is that a working government fills these rooms, and that fact reframes how you read the building. Check the official website before you go, because a sitting legislature keeps its own calendar. A palace from 1740 that still houses a parliament gives you reason to spend an hour here: you see the building and the country's politics at the same time.

4 Rosenborg Castle
A palace dating from 1606, listed on the Kulturstyrelsen monument register
Rosenborg Castle, a palace in Copenhagen dating from 1606, opens from 10:00 to 17:00 every day. We'd avoid arriving in the last hour before the 17:00 close, because a building this old deserves an unhurried visit, and a morning start gives you room to take it in. The castle is listed as a monument on the Kulturstyrelsen register, so the fabric of the place is what you have come to see, not the contents alone. It keeps the same schedule seven days a week, and few sights here match that consistency. Check the official website for anything seasonal before you set out.

5 Rundetaarn
52A Købmagergade, København K, 1150A 17th-century tower dating from 1642, listed on the Kulturstyrelsen register
Rundetaarn stands at 52A Købmagergade in 1150 København K, a 17th-century tower in central Copenhagen that dates from 1642 and is listed as a monument on the Kulturstyrelsen register. The hours are worth reading closely: from May to September it is open daily from 10:00 to 20:00, and from October to April it opens at 10:00 and closes at 18:00 on most days but stays open until 21:00 on Tuesdays and Wednesdays. The locals know those late winter evenings are the calmer time to come. We'd skip the crowded midday slot in summer and use the long opening hours: a summer evening visit before the 20:00 close is the better way to see it.

6 Grundtvig's Church
På Bjerget, København NV, 2400A church dating from 1940, open late on Thursdays
Grundtvig's Church sits on På Bjerget in the 2400 København NV postal area, opening at 09:00. Monday to Wednesday, Friday and Saturday it closes at 16:00, but Thursday stretches to 18:00, which is the day we'd choose. Sunday isn't listed among the visiting hours, so plan on a weekday. A building from 1940 may seem outranked by the city's older churches, but that is exactly the wrong approach: this is what a 20th-century church looks like when treated as a main sight rather than an afterthought, and it earns the trip. The extra two hours on Thursday until 18:00 take the pressure off. Check the official website first.
Dates from 1940
Hours: Mo-We, Fr-Sa 09:00-16:00; Th 09:00-18:00

7 Amalienborg
The palace and home of the Danish royal family
A royal household still lives at Amalienborg, the palace and home of the Danish royal family in Copenhagen, and that is what sets it apart. It dates from 1760 and is listed as a monument on the Kulturstyrelsen register. Don't treat it like a museum to be worked through room by room. What draws you here is that it's a royal home still in use, a place where people live and work rather than a set piece, and that reframes how you see it. A building from 1760 that is still a family home rewards a slow walk around it more than a checklist does. Give it half an hour of unhurried looking.

8 Frederik's Church
Frederiksgade, København K, 1265A church dating from 1749, open every day of the week
Frederik's Church on Frederiksgade in 1265 København K opens at 10:00 Monday to Thursday. The rest of the week runs differently: Friday not until 12:00, Saturday at 10:00 and Sunday at 13:00, with every day closing at 17:00. Arriving on a Friday morning is the surest way to find a locked door, so don't plan the visit that way. The church dates from 1749, and a building that old deserves a proper visit rather than a glance on the way somewhere else. A weekday at 10:00 gives you the quietest hours. Check the official website before you go.
Dates from 1749
Hours: Mo-Th 10:00-17:00; Fr 12:00-17:00; Sa 10:00-17:00; Su 13:00-17:00

9 Church of Our Lady
Nørregade, København K, 1165The cathedral of Copenhagen and the National Cathedral of Denmark
The Church of Our Lady, Copenhagen's cathedral and the National Cathedral of Denmark, stands on Nørregade in 1165 København K and dates from 1829. It opens Monday to Saturday, 08:00 to 17:00, so plan it for a weekday: Sunday is not among the listed hours. Come close to 08:00, because few sights in the city open this early, and arriving then gives you a national cathedral that still feels like a working church rather than a stop on a tour route. Skip the late-afternoon slot. Check the official website for services before you go.
Dates from 1829
Hours: Mo-Sa 08:00-17:00

10 Church of Our Saviour
Sankt Annæ Gade, København K, 1416A church dating from 1695, open daily for a short window
The Church of Our Saviour sits on Sankt Annæ Gade in 1416 København K and opens every day from 11:00 to 15:30. That window is short, and it shapes the whole visit. The church dates from 1695, which makes it one of the older buildings in this selection, and a building of that age deserves more than a rushed half-hour before the 15:30 close. Come close to 11:00 and give it the time it asks for. Check the official website before you set out, since a tight schedule leaves no room for surprises.

11 Copenhagen Opera House
An opera house in Copenhagen dating from 2005
Opera, not sightseeing, is the reason the Copenhagen Opera House exists: it is an opera house in Copenhagen that dates from 2005. Skip the walk-by photo of the outside. The building earns its place when it is doing its job, so check the programme on the official website and plan an evening around a performance. No list of what to see here is complete without at least one place where the culture is happening now rather than preserved, and a house from 2005 stands for the city that is still building, beside the palaces and churches that show what it has kept. Book ahead, dress however you like, and give the night to the music.

12 St. Ansgar's Cathedral
Bredgade, København K, 1260A Catholic cathedral in Copenhagen dating from 1842
St. Ansgar's Cathedral sits on Bredgade in the 1260 København K postal area, a Catholic cathedral that dates from 1842, and it offers something the crowded headline churches don't: room to sit quietly rather than file through. A cathedral from 1842 belonging to a Catholic congregation shows you a side of the city's religious life that the national church elsewhere on this list cannot. No visiting hours are listed here, so check the official website before you go rather than turning up on chance. We'd go on a weekday, keep voices down, and give it a few unhurried minutes.
