Known for its cultural and historical attractions, Odessa is often referred to as the "Pearl of the Black Sea". Founded by Catherine the Great in the late 18th century, it later thrived under refugee Cardinal Richelieu. This Ukrainian town is now a center of industry and shipping as well as a popular coastal resort where visitors come to experience its "curative muds." Start your exploration at the top of Potemkin Steps and enjoy a magnificent harbor view. Plan to visit the Odessa Opera Theatre where famous Russian ballets are performed.
