In 1945, after the bombing, the revolts, the fighting, and the demolition had ended, most of Warsaw lay in ruins. Next to the remnants of Gothic architecture the ruins of splendid edifices from the time of
Congress Poland and ferroconcrete relics of prewar building jutted out of the rubble. The symbols of the new Warsaw were: •
Warsaw W-Z Route ("Trasa W-Z") under the Old Town (1949) • MDM estate (1952) (typical socialist realism architecture) •
Palace of Culture and Science (PKiN, 1955) a symbol of Soviet rule, and at that time the second tallest building in Europe •
10th-Anniversary Stadium (1955). Construction of the MDM estate and PKiN especially required demolishing existing buildings. Demolition, however, made it possible to create one of the street plans in Europe, aside from poor road conditions and badly planned crossroads. , symbol of
Soviet domination in Poland. In 1951, Warsaw was significantly enlarged again to address the housing shortage: from to . In 1957, the town
Rembertów was incorporated. On the incorporated areas, the city's government ordered the building of mainly large
prefabricated housing projects, typical for Eastern Bloc cities. The Soviet presence, symbolized by the Palace of Culture and Science, turned out to be very acute. Stalinism lasted in Poland until 1956—as in the USSR. The leader (
First Secretary) of the
Polish United Workers' Party, (
PZPR),
Bolesław Bierut, suddenly died in Moscow during the
20th Congress of CPSU in March, probably from a heart attack. By October, the new First Secretary,
Władysław Gomułka, in a speech during a rally on the square in front of the PKiN supported the regime liberalization (so-called "thaw"). At first, Gomułka was very popular, because he also had been imprisoned in
Stalinist prisons and as he had taken up the office of PZPR's leader, he promised a lot, but the popularity faded quickly. Gomułka was gradually tightening the regime. In January 1968, he forbade the performance of
Dziady, a classical drama by
Adam Mickiewicz, full of anti-Russian allusions. That was "the last drop of bitterness": then students went out on the Warsaw streets and gathered by the monument to Mickiewicz to protest against censorship. The demonstrations spread throughout the country, and the protestors were arrested by police. This time, the students were not supported by workers, but
two years later, when in December 1970 the
Polish People's Army fired at the protesting people in
Gdańsk,
Gdynia and
Szczecin, those two social groups cooperated—and that helped end Gomułka. Mass in
Victory Square, 1979. Gomułka was succeeded by
Edward Gierek. Compared to the
grey Gomułka time, Gierek ruled with a lighter hand. Once in office, Gierek agreed to rebuild the Royal Castle. Gomułka was against this idea until the end of his life, because he was convinced that the Castle was a symbol of the bourgeoisie and feudalism. Rebuilding started in 1971, and finished in 1974—the same year the
Trasa Łazienkowska (
Łazienkowska Route) was completed. The route and bridge that connect the
Warszawa Zachodnia Station area and the Grochów estate—the broad street on the right bank (Praga)—has been named
Aleja Stanów Zjednoczonych (The United States Avenue). The next important investments from the Gierek-times are: the
Warszawa Centralna station (1975, now the biggest station in Warsaw) and the broad, dual carriageway Warsaw-
Katowice, which even now is called "Gierkówka" (in a choice of the
destination point, significantly Gierek was born in Silesia, in Sosnowiec). But the prosperity of the Gierek-times was grounded on a very fragile foundation: Gierek took out many loans from other countries and did not know how to manage them efficiently, hence from time to time crises and workers' riots recurred. The first, more serious was in 1976, when workers from
Radom and
Ursus were striking; that latter city bordered on Warsaw from west, and had a large tractor factory. As a penalty, Ursus was incorporated into Warsaw as a part of the district Ochota; Warsaw expanded by . In the crisis of the 1980s and hard time of
martial law,
John Paul II's visits to his native country in 1979 and 1983 brought support to the budding
Solidarity movement and encouraged the growing anti-communist fervor there. In 1979, less than a year after becoming pope, John Paul celebrated Mass in
Victory Square in Warsaw and ended his sermon with a call to "renew the face" of Poland: Let Thy Spirit descend! Let Thy Spirit descend and renew the face of the land! This land! In 2002, city
Wesoła was incorporated into Warsaw and capital of Poland expanded again by another . In March 2021, plans were announced to add a third line to the city’s metro system, connecting the city centre with the district of
Praga-Południe on the right (east) bank of the Vistula river, and later also with
Ochota and
Mokotów as a major part of a wider “New Opening” project that also included new pedestrian and cycling infrastructure in central parts of Warsaw. On 28 September 2022, three new Warsaw metro stations were opened, increasing the number of Warsaw Metro stations to 36 and its length to 38,3 kilometers. In February 2023, Warsaw’s mayor,
Rafał Trzaskowski, announced plans to more than double the size of the city’s metro system by 2050. With the entry of Poland into the
European Union in 2004, Warsaw experienced the biggest economic boom of its history. Another important stimulator of the economy was the
European football championship in Poland and Ukraine in 2012. Five matches, including the opening match, took place in Warsaw. The city also hosted the
2013 United Nations Climate Change Conference and the
2016 NATO Summit. As of August 2022, Warsaw had received around 180,000 refugees from Ukraine, because of the
2022 Russian invasion of Ukraine. The amount means a tenth of the Polish capital’s population of 1.8 million — the largest single group of Ukrainian refugees anywhere. ==Historical images==
