Staff at the Hammersmith Polish centre enjoyed a day at the Queen's Park Rangers (QPR) football ground after the club invited them to watch a match as a sign of solidarity.
The invite to Loftus Road came after the centre was sprayed with abusive graffiti which shook the west London community .
It coincides with Mayor Sadiq Khan's new campaign named #LondonIsOpen, reminding the world and city that the capital welcomes all after the European Referendum vote saw the country opt for Brexit .
QPR FC declared their backing of the campaign and celebrated their Polish connections at Loftus Road Stadium by welcoming the Deputy Polish Ambassador Dariusz Łaska and staff from the Polish cultural centre (POSK) in Hammersmith to the game on Sunday (August 7).
Mr Khan said: "#LondonIsOpen will show the world that London remains entrepreneurial, international, and full of creativity and possibility, while reassuring the more than one million foreign nationals who live in London that they will always be welcome, and that any form of discrimination will not be tolerated."
The Labour Mayor added: "Sport is in the spotlight this month, with events from the 2016 Olympics and Paralympics in Rio de Janeiro to football season opening games in London getting people geared up to cheer on their team.
"In this great city, we don’t just tolerate difference, we celebrate it, and it’s fantastic to see Queens Park Rangers opening its arms to the Polish community in this show of solidarity.”
Turner prize winner David Shrigley is among the 10 artists whose work makes up the campaign, posters of which are found across London's Underground.
QPR co-chairman Tony Fernandes added: " We’re delighted to welcome supporters of all nationalities to Loftus Road as we kick off this season, and for the chance to show our solidarity with the Polish community, including the many Polish QPR supporters and, of course, our own new signing Ariel Borysiuk .
"We’re lucky enough to have fans from all over the world and, as part of our support of the #LondonIsOpen campaign, we want to make clear that wherever you’re from, our club, and our capital, are open to all.”
Deputy Polish Ambassador Dariusz Łaska said:
“We welcome QPR’s show of support for the 200,000 Poles who live and work in the capital.
"It is an important message, especially after the attack on POSK and other incidents of xenophobic abuse that shocked the Polish community.
"London has a very special place in every Pole’s heart.
"It was the refuge of the Polish Government-in-Exile and free Poles during the Second World War and the time of communism.
"The Polish community is a mixture of the descendants of those wartime and anti-communist exiles and those who decided to move to Britain after Poland joined the EU, who all equally contribute to the capital’s society, economy, and indeed sport.”
Councillors and MPs urged communities they are, and always will be, welcome in west London after the Metropolitan police reported on a sharp rise in hate crime in recent weeks, leading to increased police patrols .
