Sofia Province (Bulgarian: Софийска област, romanized: Sofiyska oblast) is a province (oblast) of Bulgaria. The province does not include Sofia in its territories, but Sofia remains the seat of its administration. The province borders on the provinces of Pernik, Kyustendil, Blagoevgrad, Pazardzhik, Plovdiv, Lovech, Vratsa, Montana, and "Sofia City Province" (which is in a separate oblast, see Sofia Administration), and borders with Serbia to the northwest.

The City of Brussels is the largest municipality and historical centre of the Brussels-Capital Region, as well as the capital of the French Community of Belgium, the Flemish Region (from which it is separate) and Belgium. The City of Brussels is also the administrative centre of the European Union, as it hosts a number of principal EU institutions in its European Quarter.

Besides the central historic town located within the Pentagon, the City of Brussels covers some of the city's immediate outskirts within the greater Brussels-Capital Region, namely the former municipalities of Haren, Laeken, and Neder-Over-Heembeek to the north, as well as the Avenue Louise/Louizalaan and the Bois de la Cambre/Ter Kamerenbos park to the south-east, where it borders municipalities in Flanders.

Department of Cundinamarca (Departamento de Cundinamarca, Spanish pronunciation: [kundinaˈmaɾka]) is one of the departments of Colombia. Its area covers 22,623 square kilometres (8,735 sq mi) (not including the Capital District) and it has a population of 2,919,060 as of 2018 (3,445,300, DANE 2023 projections). It was created on August 5, 1886, under the constitutional terms presented on the same year. Cundinamarca is located in the center of Colombia.

Cundinamarca's capital city is Bogotá, the capital of Colombia. This is a special case among Colombian departments, since Bogotá is not legally a part of Cundinamarca, yet it is the only department that has its capital designated by the Constitution (if the capital were to be ever moved, it would take a constitutional reform to do so, instead of a simple ordinance passed by the Cundinamarca Assembly). In censuses, the populations for Bogotá and Cundinamarca are tabulated separately; otherwise, Cundinamarca's population would total over 11 million.

Viken was a short-lived county in Norway that existed from 1 January 2020 to 1 January 2024. Its name was derived from the historical region in present-day Norway and Sweden. The county was located in Eastern Norway when it was established on 1 January 2020 by the merger of Akershus, Buskerud and Østfold with the addition of the municipalities of Jevnaker, Lunner and the former Svelvik Municipality. Both its creation and its name—described as unhistorical by historians—were controversial from the onset, the merger was resisted by all the three counties and the new county had an approval rating of about 20% in the region. Viken has been compared to gerrymandering. The newly constructed coat of arms of Viken lacked a historical basis and was described by experts as an amateurish logo that did not adhere to the rules of heraldry, and as "three flying saucers under a cap." The county executive of Viken determined in 2019, before the merger had taken effect, that the county's disestablishment was its main political goal, and the formal process to dissolve Viken was initiated by the county executive right after the 2021 Norwegian parliamentary election in which parties seeking to reverse the merger won a majority. The political platform of the government of Jonas Gahr Støre stated that the government would dissolve Viken and re-establish Akershus, Buskerud and Østfold based on a request from the county itself. On 22 February 2022, the regional assembly of Viken approved the formal request to disestablish the county, and the disestablishment took effect on 1 January 2024.

Viken was home to over 1.2 million people, or 23% of the national population. The county seat was the national capital, Oslo, which was an enclave of Viken and is not part of the county. Oslo had been the seat of Akershus county since the Middle Ages. All of Viken was located in the historical Akershus, which included much of Eastern Norway. The county took its name from the historical region of Viken, which has been defined as an area in Bohuslän, in what is now western Sweden, since the late Middle Ages, but which was formerly used loosely for the region around the Oslofjord in the earlier middle ages.
