Lawrence (in c. 1920) and Eric Whelpton (in 1950s) and the Belgian Jules Destrée (in 1915 and in 1930) visited Reggio. Geography With an exceptionally high population density, Reggio Calabria was cited as having the least green space in a study of 386 European cities. The study reported that green space coverage varied markedly, averaging 18.6 per cent and "ranging from 1.9 (Reggio di Calabria, Italy) to 46 (Ferrol, Spain) per cent." The study further reported "Per capita green space provision varied by two orders of magnitude, from 3 to 4 m2 per person in Cádiz, Fuenlabrada and Almería (Spain) and Reggio di Calabria (Italy) to more than 300 m2 in Liège (Belgium), Oulu (Finland) and Valenciennes (France)." Even so, outside of the urban area, the nearby elevated areas have plenty of green space and extensive forests. This includes the Aspromonte National Park. Climate According to the Köppen climate classification, Reggio Calabria possesses a typical Mediterranean climate (Köppen: Csa). Its climate has warmer days and cooler nights than Messina which lies on the other side of the strait. Precipitation is another big difference since Messina receives approximately more.
