Which European capital city is served by the airport named Bromma?

Bromma Stockholm Airport (formerly Stockholm-Bromma Flygplats) is a Swedish domestic and minor international airport in Stockholm. It is located 4 nautical miles (7.4 km; 4.6 mi) west-northwest of downtown Stockholm and is the closest to the city compared to the other commercial passenger airports in the area around Stockholm (Arlanda, Skavsta and Västerås). Bromma is Sweden's third-busiest airport by passenger traffic and take-offs and landings as of 2015.

Expansion of the airport would be limited by noise issues, a lack of space, and the necessity to preserve the cultural heritage (the airport buildings). With the completion of the third runway at Stockholm Arlanda Airport there is a capacity surplus at that airport, and there have been ongoing debates on whether to use the land occupied by Bromma Airport for residential and commercial purposes for several years.

When the airport opened in 1936 the surrounding area was mostly rural, however as the city has expanded noise has become an issue. Therefore, certain measures have been put in place, such as limiting airport operations to the daytime, limiting the type of commercial aircraft which are allowed to operate from the airport and soundproofing residential homes near the airport.
