Naples, Italy, is known as the birthplace of what is arguably the world's most recognizable dish — pizza. But only 3,000 pizza bakers are officially recognized Pizzaiuoli, and can use the traditional wood-fired oven and dough preparation techniques.

Yoga is not only physical exercise, but a mental and spiritual one as well. Yoga originated in India in the fifth century BC, and is used to "help individuals build self-realization, ease any suffering they may be experiencing and allow for a state of liberation."

Falconry, the art of training falcons, was originally used as "a method of obtaining food," but has since evolved into a method of social engagement and nature conservation.

Tango developed from European, African and Native American dancing traditions in the 1880s along the border between Argentina and Uruguay.

Vienna's Spanish Riding School was added to UNESCO's list in 2015. Named for the Spanish horses that formed the base of the riding hall's Lipizzan breed, the school was first formed by the Hapsburg monarchy in 1572.

Despite its small size, Belgium produces nearly 1,500 different types of beer. Some of the most popular are produced by Trappist monks, who donate their profits to charity. Beer is such a part of everyday life in Belgium that up until the 1960s, beer was an option at school lunches.

Known for its elaborate make-up and stylized drama, Kabuki theatre originated in 17th century Japan and was originally performed only by women. Kabuki plays follow one of three categories — history, domestic tales, and dance pieces. The word kabuki can be roughly translated to "avant-garde."
