NGUC celebrated its tercentenary in 2008 under the slogan "300 years of dissent", marking this with events such as planting a crab apple tree, organising a picnic in conjunction with the Newington Green Action Group, and hosting a concert of Ottoman classical music. (Newington Green has a strong Turkish population.) The following year it commemorated the 250th anniversary of the birth of Mary Wollstonecraft, attaching a large banner to the railings outside the building, proclaiming it the "birthplace of feminism", in a nod to the formative years that she spent worshipping there. NGUC sponsored a series of events, including a return visit and lecture by biographer Barbara Taylor; a panel discussion about women and power, between female politicians Diane Abbott MP, Jean Lambert MEP, and Emily Thornberry MP; an art exhibition entitled Mother of Feminism; a concert featuring Carol Grimes and Adey Grummet to raise money for Stop the Traffik, an anti-trafficking charity; a tombstone tribute at St Pancras Old Church; a birthday cake baked by men; and other activities.
