In October 2025, Royal Museums Greenwich hosted the Queer Migrations Festival, a community event exploring the connections between queerness and migration through art, performances, and workshops. Activities took place at the Firepit Art Gallery and as part of PARKSfest. The festival highlighted stories of transnational bodies, identity, and generations, with a particular emphasis on LGBTQ+ rights and intersectional feminism. The event attracted queer activists and artists from across the United Kingdom. This cultural initiative promoted inclusion within historic spaces, aligning with broader debates on migration and gender rights in the post-Brexit era.
