The Grand Place in Brussels is said to be one of the most beautiful squares in Europe and i agree. All those buildings are really beautiful.
La Grand-Place in Brussels is a remarkably homogeneous body of public and private buildings, dating mainly from the late 17th century. The architecture provides a vivid illustration of the level of social and cultural life of the period in this important political and commercial centre. - in: http://whc.unesco.org/en/list/857
This official shows 2010 Flower Carpet made with 750.000 begonias.
Officially, the first flower carpet was born in 1971 on the Grand-Place. It was the work of the landscape architect E. Stautemans, who was inspired by other carpets created in diverse Flemish cities. The peculiarity of the Brussels Flower carpet is of course its place on the Grand-Place.
This carpet of 77 m X 24 m is realized in several stages. It is planned one year in advance. Projects with scale reproductions are elaborated on the basis of the subject. The number of flowers and the combinations of colors are then determined.
The life-size drawing of the carpet is put on a transparent and micro-drilled plastic sheet. The carpet then has to be made by approximately 120 volunteers who install near a million begonias (at the rate of 300 by m3) within 4 hours. - in: http://www.brussels.be/artdet.cfm/4310
