Note that, even if not universal, it is quite usual among the Oslo population to pronounce Frogner more close to the spelling 'Frongner' rather than Frogner (some do say Frogner as well, both are allowed).

A majority of the houses in the borough were built around 1900. Frogner has historically been and continues to be an affluent area of Oslo.

Frogner Church (Norwegian: Frogner kirke) is a church in the Frogner borough of the city of Oslo, Norway. The congregation is part of the Church of Norway, the country's state church.

Frogner is home to several restaurants and bars - including Feinschmecker, Alex Sushi and Bagatelle, while a range of caf├ęs offer simpler food.
