Historically, the City of Brussels was simply defined, being the area within the
second walls of Brussels, the modern-day
Small Ring (Brussels' inner ring road). As the city grew, so did the surrounding villages, eventually forming a contiguous city, though the local governments retained control of their respective areas. and its walls , by
Jan Baptist Bonnecroy At the
country's independence in 1830, the new members of the Belgian upper class hoped to create a new prestigious residential area in the capital. An official plan for the
Leopold Quarter was drawn up in 1838, marking the first major extension of the City of Brussels in its eastern part, following the transfer of a large area of the municipality of
Saint-Josse-ten-Noode. The area was designed to emanate from
Brussels Park (located in front of the
Royal Palace), and was laid out on a grid in a traditional classical pattern centred around the /. Shortly afterwards, in 1844, the
Avenue Louise/Louizalaan was proposed as a monumental avenue bordered by
chestnut trees that would allow easy access from
Brussels' city centre to the popular recreational area of the
Bois de la Cambre/Ter Kamerenbos. However, fierce resistance to the project was put up by the towns of
Saint-Gilles and
Ixelles—then, as now, separate municipalities (local authorities) from the City of Brussels—through whose territories the avenue was to run. After years of fruitless negotiations, the City of Brussels finally annexed the narrow band of land needed for the avenue, in addition to the Bois de la Cambre itself, in April 1864. Unlike most of the municipalities in Belgium, the ones now located in the Brussels-Capital Region were not merged with others during mergers occurring in 1964, 1970, and 1975. However, a few neighbouring municipalities have been merged into the City of Brussels, including
Haren,
Laeken and
Neder-Over-Heembeek in 1921. These comprise the northern bulge in the municipality. To the south-east is the above-mentioned strip of land along the Avenue Louise that was annexed from Saint-Gilles and Ixelles. Part of the (ULB)'s
Solbosch/Solbos campus is also part of the City of Brussels, partially accounting for the bulge in the south-eastern end. ==Demographics==
