De Rotterdam is conceived as a vertical city: three interconnected mixed-use towers accommodating offices, apartments, a hotel, conference facilities, shops, restaurants, and cafes. The project began in 1997. Construction started at the end of 2009, with completion in 2013. The towers are part of the ongoing redevelopment of the old harbour district of Wilhelminapier, next to the Erasmus Bridge, and aim to reinstate the vibrant urban activity – trade, transport, leisure – once familiar to the neighbourhood. De Rotterdam is named after one of the ships on the Holland America Line, which departed from the Wilhelminapier in decades past, carrying thousands of Europeans emigrating to the US.
