What is casino.
A casino is a facility that houses and accommodates certain types of gambling activities. Casinos are most commonly built near or combined with hotels, restaurants, retail shopping, cruise ships and other tourist attractions.
The term "Casino" is of Italian origin, the root word being "Casa" (house) and originally meant a small country villa, summerhouse or pavilion. The word changed to refer to a building built for pleasure, usually on the grounds of a larger Italian villa or palazzo. Such buildings were used to host civic town functions - including dancing, music listening and gambling.
During the 19th century, the term "casino" came to include other public buildings where pleasurable activities, including gambling, and sports took place.
