In the 19th century the city had a small but active Polish population that increased during the century to account for 1.5% of the population by 1905. The Polish community funded a Catholic school and the Church of Saint Marcin where masses in Polish were held (initially throughout the season, after about 1890 all the year), were established. Dating back to 1261 Kolberg's Jewish population amounted to 528 people in 1887, rising to 580 two years later, and although many moved to Berlin after that date they numbered around 500 by the end of the Nineteenth century
