From Cairo to Tokyo: Can you guess these twin cities?

As a London borough moves to cut ties with Haifa, test your knowledge of the world’s twin cities.

Hackney, a borough in east London, is consulting residents until October 14 on whether to end its twinning with Haifa, Israel’s third-largest city, a link that dates back to 1968.

The Green Party-led council voted on July 28 to end the partnership in principle, citing its values and human rights commitments amid Israel’s genocidal war on Gaza. Councillors will make a final decision after the consultation and a review of the borough’s twinning policy.

What are twin cities?

Twin cities, also called sister cities, are places in different countries linked by formal friendship agreements. These relationships can support school exchanges, cultural events and civic visits, though many become inactive over time.

Can you guess which cities are twinned? Take our quiz below.

How twin cities began

Modern town twinning grew after World War II as a way to rebuild trust and foster peace. Coventry and Stalingrad (now Volgograd), both heavily bombed during the war, established a friendship link in 1944, often cited as the first modern city-twinning relationship.

The US city of St Paul and Japan’s Nagasaki established a sister-city partnership in 1955 to promote reconciliation after the atomic bombing of the latter in 1945. Cities have since formed links because of shared histories, similar roles as capitals or ports, or communities with roots in both places.

Why do cities cut ties?

Because twinning is often symbolic, ending a link can allow a council to make a statement. Several UK councils suspended or ended links with Russian cities after the 2022 invasion of Ukraine.

Prague’s relationship with Beijing also ended in 2019 amid a dispute involving Taiwan, after which the Czech Republic established a partnership with Taipei. Hackney’s proposal is the latest example of cities reassessing their international ties.
