Østerbro

Brumleby is a small quarter nestled in a triangle between Trianglen square and the National Stadium. It was build in the 1850's by the Danish Medical Association, as answer to a recent cholera epidemic, as a showcase on how to make healthy but affordable housing for the working class. It has been awarded Europa Nostra award for conservation, and it is a nice place for a brief stroll if you are in the area. There is a small museum in the old cooperative shop and a exhibitions space for local artists, but both have random opening hours.

Kastellet

A superbly preserved and restored star-shaped citadel. First built in 1626 as St. Anne's Bulwark and completed in 1664, it was the stronghold at the northern end of the East Rampart, which arched through the city and remains in the form of the many parks extending down to Tivoli. The Citadel now houses the Danish Defense Intelligence Service, and is a popular spot for picnics.

This museum is run by the University of Copenhagen. In the exhibitions, you can experience how the fauna changes as you travel from the North Pole to the South Pole, the Danish fauna since the Ice Age, including a 3 meters tall mammoth and the animals of the great oceans. The latest progress in science is brought to life in some very good temporary exhibitions.

This collection was founded by the Copenhagen-born tobacco manufacturer Heinrich Hirschsprung 1836-1908, and moved into the current museum after his death in 1911. The museum hosts an impressive collection of Danish 19th-century art in a beautiful building displaying furniture from the artists homes.

This museum opened in 1957 and is just outside Kastellet which was occupied by German forces from 1940 to 1945. The exhibition proceeds chronologically as an illustration of how the resistance movement developed.

King Christian IX's daughter Alexandra, who was became the Queen of England was the driving force behind the erecting of this church, which is home to the English congregation in Denmark. The church was completed in 1887, and was built with some impressive flint stone walls.

A small museum run by the Danish tax and customs authority, detailing its history in various exhibitions. The most interesting part is displays of various ingenious ideas and contraptions used in smuggling attempts through the ages. Mainly geared towards Danes, so it is probably not worth a trip, unless you are around Langelinie already.

Den lille Havfrue

This little lady is one of the most photographed in the world. Designed by Edvard Eriksen, Her statue was erected in 1913 to commemorate a play of the Little mermaid. The poor lady has lost her head several times, and is often subject to vandalism connected with political statements. Many visitors are often surprised by her modest size 1.25 m (3.3 ft high). The Little Mermaid is a semi official symbol of Copenhagen.

This mini-district was built in the 17th century, and consists of long rows of beautiful 2 story yellow brick buildings. It was built to house sailors from the Navy, as it was useful to have sailors in the fleet living in a confined space, so they could quickly be called to duty. Even to this day the houses are inhabited only by people connected to the navy. On Sankt Pauls Gade 24, Nyboder mindestuer showcases everyday life in the neighborhood from its inception in 1631, every Sunday between 11AM-2PM.

This art exhibition was established in 1891, as a protest against a censored exhibition sponsored by the royal art board — hence the name. Mainly shows contemporary art. The exhibition is housed in a remarkable, recently restored building that resembles an ancient Greek temple.
