of the Jews who were deported via Loods 24 were murdered in Sobibór and Auschwitz-Birkenau. Research in 2000 showed that 144 people survived the deportations. In 2013 the Jewish Children's Monument was unveiled. In January 1948, Queen Wilhelmina presented the motto 'Sterker door strijd' (Stronger through effort) as part of the coat of arms of Rotterdam to the city government: ...as a reminder also for posterity of the courage and strength with which the people of Rotterdam bore all the trials of the war and the important part they took in the liberation of the fatherland.... —Wilhelmina of the Netherlands Rotterdam was gradually rebuilt from the 1950s through to the 1970s. Because the city centre was largely destroyed, new spatial infrastructure could be built, making it an open and modern city. In 1953 the Lijnbaan was opened, the first car-free shopping street in Europe. The progressive design attracted a lot of international attention. The new Central Station was completed in 1957, with the Groothandelsgebouw from 1953 next to it. The Euromast was erected in 1960 on the occasion of the Floriade. From the 1980s onwards the city councils began developing an active architectural policy. The harbours were moving westwards and the old environment had to be reshaped. Daring and new styles of apartments, office buildings and recreation facilities resulted in a more 'livable' city centre with a new skyline. In the 1990s, the Kop van Zuid was built on the south bank of the river as a new business centre. Rotterdam was voted 2015 European City of the Year by the Academy of Urbanism. A profile of Rem Koolhaas in The Guardian begins "If you put the last 50 years of architecture in a blender, and spat it out in building-sized chunks across the skyline, you would probably end up with something that looked a bit like Rotterdam." Geography Rotterdam is divided into a northern and a southern part by the river Nieuwe Maas, connected by (from west to east): the Beneluxtunnel; the Maastunnel; the Erasmusbrug; a subway tunnel; the Willemsspoortunnel ('Willems railway tunnel'); the Willemsbrug ('Willems Bridge') together with the Koninginnebrug ('Queen's Bridge'); and the Van Brienenoordbrug ('Van Brienenoord Bridge'). The former railway lift bridge De Hef ('the Lift') is preserved as a Rijksmonument (national heritage site) in lifted position between the Noordereiland ('North Island') and the south of Rotterdam. The city centre is located on the northern bank
