Overview

The Observatory district began to develop between 1870 and 1914, with a number of townhouses and villas built on the green edges of the Saint-Job plateau. This early period was characterised by English cottage-style country houses, with overhanging roofs, polygonal floor plans and an abundant use of wood. At the same time, Art Nouveau was developing in the centre of Brussels. Discreet traces of this can be found in the Observatory district, such as Victor Horta’s Villa Frison. The Royal Observatory of Belgium, founded by mathematician Alphonse Quetelet and built by Octave Van Rysselberghe, is the district’s most renowned scientific institution. Art Deco and modernism are also well represented in the district. Great Belgian architects such as Adrien Blomme, Henry Van de Velde and Victor Dirickx designed homes here. Contemporary architecture also made its mark, with landmark projects by architects such as Jacqmain, Bontridder and Dupuis. In collaboration with Korei Guided Tours.
