More than 500 parents and children joined Jewish education charity Seed for its Pizza in the Hut Succot activity.
The annual event, part of the Wohl family education programme, delivered hot pizza to London Jewish schools Immanuel, Sobell Sinai, Wolfson Hillel, Rosh Pinah and Etz Chaim. Activities were designed for parents to participate with children - from arts and crafts to a carnival.
Seed's Rabbi Malcolm Herman said the organisation was "about strengthening the family through positive Jewish encounters and a shared enjoyment of Jewish life and values. We hope events like this inspire families to keep enjoying their Judaism."
Wolfson Hillel parent Lana Witcover said the activity had "made Succot even more special.
"My son was thrilled to show us the gorgeous succah model he made. The warmth all the team show is something one needs to experience to fully understand."
