What is the hot region located at the heel of Italy's boot?

The heel of Italy's boot refers specifically to the region known as Apulia, or Puglia in Italian. This region is characterized by its warm Mediterranean climate, which is conducive to the cultivation of various agricultural products, particularly olives and grapes. Apulia's geographical location on the Adriatic coast influences its weather patterns, making it one of the hottest areas in Italy, especially during the summer months. The landscape is also marked by its unique trulli—traditional stone huts—further distinguishing Apulia from other regions.

Calabria, while also a warm region located on the toe of Italy's boot, is not considered the heel. Sicily, which is an island, is situated to the southwest of the mainland and has its own distinct climate and geography. Basilicata, located just above Apulia, has a more mountainous terrain and is not as hot as Apulia. Thus, Apulia is accurately identified as the hot region at the heel of Italy's boot due to its climate, cultural significance, and agricultural output.
