Sopot is a seaside spa resort city in Poland. Sopot and two nearby cities, Gdańsk and Gdynia, are often referred as Tricity (Polish: Trójmiasto ). It is a smallest of the three and the most affluent on average, attracting the rich and famous from the local area (who tend to settle there), and from Poland, Europe and elsewhere, who come over for vacations or maintain a pied- a-terre there.
