The name of the new south square in the Westgate development was announced at an unveiling last weekend.
It will be named Leiden Square to celebrate the 70th anniversary of the twinning link between Oxford and the Dutch city.
With Leiden Square to the south of the new Westgate Quarter, and Bonn Square to the north, the name commemorates Oxford’s links with its two oldest twin cities.
Leiden Square was officially unveiled at the Oxford European Association reception at the Town Hall on Saturday.
The reception, which was hosted by the Lord Mayor of Oxford, councillor Mohammed Altaf-Khan and Oxford City Council leader, councillor Bob Price, welcomed visitors from the twin cities who were visiting Oxford for the Remembrance weekend.
The Burgemeester of Leiden, Henri Lenferink, and the Burgermeister of Bonn, Helmut Kollig, were all present, as was Pascal Clouaire, Adjoint to the Mayor of Grenoble responsible for international links.
Cllr Price said: “Oxford is proud of its longstanding links to cities in Europe and throughout the rest of the world.
“The naming of the new Leiden Square is an opportunity to commemorate our friendship in a permanent form as we approach the 70th anniversary of twinning with the city, and to remember the tragic events of the Second World War which brought the three cities of Bonn, Leiden and Oxford together.”
Sara Fuge, development manager for the Westgate Alliance, said: “We are delighted that visitors to Westgate Oxford will be able to enjoy using the new Leiden Square when we open in October 2017.
“This exciting new space in the heart of our scheme will be somewhere for everyone to enjoy, whether it’s a stop-gap from shopping or eating out, to rest and take in your surroundings, or to enjoy the events that we will host here.
“We are pleased that the name of the square has such an important meaning to Oxford and look forward to welcoming everyone next year.”
Next year, on Remembrance weekend, the city council is planning to unveil a plaque in the square to mark the 70th anniversary in a ceremony which will be attended by the Burgemeester of Leiden.
Work began in March last year and the finished project is set to include more than 100 stores, 25 restaurants and cafés.
