Scenes featuring the Gringotts Wizarding Bank (the only known wizarding bank run by Goblins) were shot inside the majestic Australia House on Strand. As the name suggests, the building is home to the Australian High Commission, which is the diplomatic mission of Australia in the United Kingdom. It is not open to the public for obvious reasons, but try asking the security guards nicely if you can take a quick peek inside. If that fails, you’re still allowed to fangirl and take a few photos in front of the building’s marvelous white facade.
