of new plants, trees and objects of 'small architecture', are underway. Numerous buildings and other constructions, including the city walls along the boulevard, are illuminated at night, creating an impressive effect - probably unique among Polish cities with respect to the size of Toruń's Old Town and the scale of the illumination project itself. Toruń is also home to the Zoo and Botanical Garden opened in 1965 and 1797 respectively and is one of the city's popular tourist attractions. Districts Toruń is divided into 24 administrative districts (dzielnica) or boroughs, each with a degree of autonomy within its own municipal government. The Districts include: Barbarka, Bielany, Bielawy, Bydgoskie Przedmieście, Chełmińskie Przedmieście, Czerniewice, Glinki, Grębocin nad Strugą, Jakubskie Przedmieście, Kaszczorek, Katarzynka, Koniuchy, Mokre, Na Skarpie, Piaski, Podgórz, Rubinkowo, Rudak, Rybaki, Stare Miasto (Old Town), Starotoruńskie Przedmieście, Stawki, Winnica, Wrzosy. Symbols The colors of Toruń are white and blue in the horizontal arrangement, white top, blue bottom, equal in size. The flag of the city of Toruń is a bipartite sheet. The upper field is white, the lower field is blue. If the flag is hung vertically, the upper edge of the flag must be on the left. The flag with the coat of arms is also in use. The ratio of the height of the coat of arms to the width of the flag is 1:2. Climate The climate can be described as humid continental (Köppen: Dfb) using the isotherm of is used or an oceanic climate (Cfb) if the isotherm is adopted. Back in 1930s, the city passed close to the original boundary and dividing line of climates C and D groups in the north–south direction proposed by climatologist Wladimir Köppen. Toruń is in the transition between the milder climates of the west and north of the Poland and the more extreme ones like the south (warmer summer) and the east (colder winter). It is not much different from the climates of more southerly Kraków and easterly Warsaw, though it has slightly milder winters and more moderate summers. Being close to definitely continental climates, it has a high variability caused by the contact of eastern continental air masses and western oceanic ones. This is influenced by the geographical location of the city – the Toruń Basin to the south, and the Vistula Valley to the north. Demographics The most recent statistics show a decrease in the population of the city,
