Since their inception, Casinos have steadily grown in size and splendor to attract big-spending patrons, extending beyond the blackjack tables and slot machines, including everything from restaurants and shopping malls to full-size roller coasters. Known for their grandiose architecture and extravagant interiors, casinos have been a societal mainstay dating back to the 17th century, starting with the Casino di Venezia in Venice, Italy.
