The mansion "Breidablikk" is well worth a visit.
It is just opposite Ledaal, the royal residence.

Breidablikk was built in 1881, and the house was given to the museum around 1970.
A Swiss style and some beautiful items shows how the middle class lived.

(Remember: Don't pay for two entrances fees if you are planning to see both places.
The ticket goes to both places.)
