Early history

Grodzisko in Sopot.

The area of today's Sopot contains the site of a 7th-century Slavonic (Pomeranian) stronghold. Initially it was a commercial trade outpost for commerce extending both up the Vistula river and to cities north across the Baltic Sea. With time the significance of the stronghold diminished and by the 10th century it was reduced to a fishing village, eventually abandoned. However, a century later the area was settled again and two villages were founded within the borders of today's city: Stawowie and Gręzowo. They were first mentioned in 1186 as being granted to the Cistercian abbey in Oliwa. Another of the villages that constitute today's Sopot, Świemirowo, was first mentioned in 1212 in a document by Mestwin I, who granted it to the Premonstratensian (Norbertine) monastery in nearby Żukowo.

The village of Sopot, which later became the namesake for the whole city, was first mentioned in 1283 when it was granted to the Cistercians. At that time it was part of Poland until the 14th-century Teutonic invasion. By 1316, the abbey had bought all villages in the area and became the owners of all the area of the city. After the Second Peace of Thorn (1466) the area was reincorporated into the Kingdom of Poland.

The spa for the citizens of Gdańsk has been active since the 16th century. Until the end of that century most noble and magnate families from Gdańsk built their manor houses in Sopot. During the negotiations of the Treaty of Oliva King John II Casimir of Poland and his wife Queen Marie Louise Gonzaga lived in one of them, while Swedish negotiator Magnus de la Gardie resided in another — it has been known as the Swedish Manor (Dwór Szwedzki) ever since.^[3] The Swedish Manor was later the place of stay of Polish Kings Augustus II the Strong (in 1710) and Stanisław Leszczyński (in 1733).^[4]

During the 1733 War of the Polish Succession, Stanisław Leszczyński stayed in Sopot a few days before going to the nearby city of Gdańsk.^[3] Afterwards Imperial Russian troops besieged Gdańsk and a year later looted and burned the village of Sopot to the ground.^[3] Much of Sopot would remain abandoned during and in the following years after the conflict, as the patricians of Gdańsk, exhausted by the war, could not afford to rebuild the Sopot residences.^[4]

In the 1750s, Polish nobility of Pomerania began to rebuild the village.^[4] In 1757 and 1758 most of the ruined manors were bought by the magnate family of Przebendowski. General Józef Przebendowski bought nine of these palaces and in 1786 his widow, Bernardyna Przebendowska (née von Kleist), bought the remaining two. Also the Sierakowski family acquired some properties, including the destroyed Swedish Manor.^[4] After the Partitions of Poland, in the 1790s, Count Kajetan Onufry Sierakowski built the Sierakowski Mansion at the site of the Swedish Manor, a typical Polish manor house, which remains one of the most distinctive buildings of pre-spa Sopot.^[5]

Kingdom of Prussia

Sopot was annexed by the Kingdom of Prussia in 1772 in the First Partition of Poland. Following the new laws imposed by King Frederick the Great, church property was confiscated by the state. The village was still being reconstructed and in 1806 the area was sold to the Danzig/Gdańsk merchant Carl Christoph Wegner. However, until 1819 it did not develop significantly, its population in 1819 was 350,^[3] compared to 301 in the year of Prussian annexation.^[5]

In 1819, Wegner opened the first public bath in Zoppot and tried to promote the newly established spa among the inhabitants of Danzig (Gdańsk), but the undertaking was a financial failure. However, in 1823 Jean Georg Haffner, a former medic of the French army, financed a new bath complex that gained significant popularity. In the following years, Haffner erected more facilities. By 1824, a sanatorium was opened to the public, as well as a 63-metre pier, cloakrooms, and a park. Haffner died in 1830, but his enterprise was continued by his stepson, Ernst Adolf Böttcher. The latter continued to develop the area and in 1842 opened a new theatre and sanatorium. By then the number of tourists coming to Zoppot every year had risen to almost 1,200.

In 1870 Zoppot saw the opening of its first rail line: the new Danzig-Kołobrzeg (then Kolberg) rail road that was later extended to Berlin. Good rail connections added to the popularity of the area and by 1900 the number of tourists had reached almost 12,500 a year.

Church of the Saviour

In 1873, the village of Zoppot became an administrative centre of the Gemeinde. Soon other villages were incorporated into it and in 1874 the number of inhabitants of the village rose to over 2,800. In 1877, the self-government of the Gemeinde bought the village from the descendants of Haffner and started its further development. A second sanatorium was constructed in 1881 and the pier was extended to 85 metres. In 1885, the gas works were built. Two years later, tennis courts were built and the following year a horse-racing track was opened to the public. There were also several facilities built for the permanent inhabitants of Zoppot, not only for the tourists. Among those were two new churches: Protestant (September 17, 1901) and Catholic (December 21, 1901). From the late 19th century, there was a significant influx of German settlers with the slow growth of the Polish population, resulting in a change in ethnic proportions in favor of the former.^[4]

Since the late 19th century the city became a holiday resort for the inhabitants of nearby Danzig, as well as wealthy aristocrats from Berlin, Warsaw, and Königsberg. Poles visited the city in large numbers and the spa was very popular among the Polish intellectual elite, to the extent that the early 20th-century Polish writer Adolf Nowaczyński named it "the extension of Warsaw to the Baltic Sea".^[4] Germans and Russians also visited the city.^[4] At the beginning of the 20th century it was a favourite spa of Emperor Wilhelm II of Germany.

On October 8, 1901, Wilhelm II granted Zoppot city rights, spurring further rapid growth. In 1904 a new balneological sanatorium was opened, followed in 1903 by a lighthouse. In 1907, new baths south of the old ones were built in Viking style. In 1909 a new theatre was opened in the nearby forest within the city limits, in the place where today the Sopot Festival is held every year. By 1912, a third complex of baths, sanatoria, hotels, and restaurants was opened, attracting even more tourists. Shortly before World War I the city had 17,400 permanent inhabitants and over 20,000 tourists every year.

Free City of Danzig

Following the signing of the Treaty of Versailles in 1919, Zoppot became a part of the Free City of Danzig in customs union with the re-established Polish Republic. Due to the proximity of the Polish and German borders, the economy of the town soon recovered. The new casino became one of the main sources of income of the free-city state. In 1927, the city authorities rebuilt the Kasino-Hotel, one of the most notable landmarks in Sopot today. After World War II, it was renamed as the Grand Hotel and continues to be one of the most luxurious hotels in Poland.

A Richard Wagner festival was held in the nearby Forest Opera in 1922. The festival's success caused Zoppot to be sometimes referred to as the "Bayreuth of the North". As a result of the influx of Germans in the previous decades, who took over the most important functions in the city, some Poles became Germanized, however a significant indigenous Polish community was still present in the city, and there was also a Jewish community.^[6] In 1928, the pier was extended to its present length of 512 metres. Since then it has remained the longest wooden pier in Europe and one of the longest in the world. In 1928, the city was visited by 29,192 visitors, mostly Poles^[6] and in the early 1930s it reached the peak of its popularity among foreign tourists — more than 30,000 annually (this number does not include tourists from Danzig itself). However, by the 1930s, tensions on the nearby Polish-German border and the rising popularity of Nazism in Germany and also among local Germans saw a decline in foreign tourism. The Nazi Party, supported by many local Germans, took power in the city.^[6] Local Poles and Jews were discriminated against^[6] and in 1938 local German Nazis burned down Zoppot's synagogue.^[3]

World War II (1939–1945)

World War II broke out on September 1, 1939, after the German invasion of Poland. The following day the Free City of Danzig was annexed by Nazi Germany and most of the local Poles, Kashubians, and Jews were arrested^[7] and murdered during the Intelligenzaktion,^[6] imprisoned or expelled. Due to the war, the city's tourist industry collapsed. The last Wagner Festival was held in 1942.

The city remained under German rule until early 1945. In March the Nazis began evacuating the German population along with forced laborers.^[6] On March 23, 1945, the Soviet Army took over the city after several days of fighting, in which Zoppot lost approximately 10% of its buildings;^[5] three days later, the Soviet 70th Army reached the Gdańsk Bay coast north of the city.^[8]

As per the Potsdam Conference, Zoppot was incorporated into the post-war Polish state and renamed Sopot. The authorities of Gdańsk Voivodeship were located in Sopot until the end of 1946. Most of the German inhabitants who had remained in the city, by 1 November 1945 6,000 Germans still lived in the town,^[9] after the evacuation before the advancing Red Army were soon to be expelled, to make room for Polish settlers from former eastern Polish territories annexed by the Soviet Union.

Polish People's Republic (1945–1989)

Sopot recovered rapidly after the war. A tramway line to Gdańsk was opened, as well as the School of Music, the School of Maritime Trade, a library, and an art gallery. During the city presidency of Jan Kapusta the town opened an annual Arts Festival in 1948. In 1952, the tramways were replaced by a heavy-rail commuter line connecting Gdańsk, Sopot, and Gdynia. Although in 1954 the School of Arts was moved to Gdańsk, Sopot remained an important centre of culture, and in 1956 the first Polish jazz festival was held there (until then jazz had been banned by the Communist authorities). This was the forerunner of the continuing annual Jazz Jamboree in Warsaw.

In 1961, the Sopot International Song Festival was inaugurated, although it was held in Gdańsk for its first three years – it moved to its permanent venue at Sopot's Forest Opera in 1964. In 1963, the main street of Sopot (Bohaterów Monte Cassino, "the Heroes of Monte Cassino") was turned into a pedestrian-only promenade.

New complexes of baths, sanatoria, and hotels were opened in 1972 and 1975. By 1977, Sopot had approximately 54,500 inhabitants, the highest ever in its history. In 1979, the historical town centre was declared a national heritage centre by the government of Poland.

Third Polish Republic (1989 onwards)

In 1995, the southern bath and sanatoria complex were extended significantly and the Saint Adalbert (in Polish Św. Wojciech) spring opened two years later, as a result in 1999 Sopot regained its official spa town status. In 1999, Pope John Paul II visited Sopot, about 800,000 pilgrims attended his mass.^[3]

In 2001, Sopot celebrated the 100th anniversary of its city charter.

Sopot is currently undergoing a period of intense development, including the building of a number of five star hotels and spa resorts on the waterfront. The main pedestrianized street, Monte Cassino, has also been extended by diverting traffic underneath it, meaning the whole street is now pedestrianized. Sopot, aside from Warsaw boasts the highest property prices in Poland.
