A chic, upmarket photography museum, Fotografiska is a must for shutterbugs. Its temporary exhibitions are huge, interestingly chosen and well presented; examples have included a Robert Mapplethorpe retrospective and portraits by indie filmmaker Gus Van Sant. Recently the museum showed an enormous collection of black-and-white photos by Sebastião Salgado. There’s also a strong permanent collection of photos from international and Swedish photographers. Follow signs from the Slussen tunnelbana stop to reach the museum.
