Motto of the city of Rotterdam, adopted in 1945 after reconstruction

The story that haunts this land

Rotterdam begins at the Stadhuis, built between 1914 and 1920 by Henri Evers in Dutch neo-Renaissance style. Its 70-meter tower, adorned with a sculpted dome, dominated Coolsingel when German bombs fell on May 14, 1940. Damaged but standing, the building today houses Isaac Israëls' frescoes painted between 1920 and 1922, witnesses to the pre-war port golden age. These walls tell the story of a municipality that refused the Nazi ultimatum and paid the heavy price.

The Grote of Sint-Laurenskerk, Gothic cathedral erected from 1449, becomes the symbol of Rotterdam resistance. The only major structure to survive the bombing, its 110 meters of length and 80-meter tower defy the flames. Inside rests Erasmus of Rotterdam, the prince of humanists who died in 1536, in a tomb sculpted by Conrad Meit in 1541. The Müller organs from 1734, with their 72 stops, still resonate despite war damage, restored in 1951 as a challenge to the silence imposed by occupiers.

Binnenrotte, the oldest market square mentioned since 1299, bears the scars of its tragic past. Center of medieval fairs since the 14th century, it was also the theater of public executions until the 18th century, notably that of 22 pirates in 1695. Its weekly flower market, established in 1870, was the largest in continental Europe until 1960. Today reconstructed, the square maintains its millennial commercial vocation, linking pre-1940 Rotterdam with the city that followed.

Facing Sint-Laurenskerk stands De Verwoeste Stad, Ossip Zadkine's bronze monument inaugurated May 15, 1954. This 6.5-meter screaming figure, cast in Paris and placed on a travertine base from ruins, embodies the pain of destruction. The biblical inscription from Jeremiah 4:20 still resonates: 'Destruction upon destruction is proclaimed.' Nearby, the 1898 Witte Huis, first Dutch skyscraper at 43 meters, miraculously survives. Sole survivor of the 25 towers in Kop van Zuid district, it was then the tallest building in Western Europe after the Eiffel Tower.

Your investigation ends at the Oude Haven quays, dug in 1350, Rotterdam's first maritime port. From here the Pilgrims embarked in 1620 on the Speedwell to America, leaving their mark at nearby Pelgrimsvaderkerk. The neo-Renaissance warehouses from the 1890s, listed in 1977, now neighbor Rotterdam Centraal station, inaugurated in 2014 with its 11,000 m² photovoltaic roof. You carry away Rotterdam's lesson: 'Sterk als vanouds, vastberaden als altijd' — a city that transforms every destruction into rebirth, every scar into new strength.
