This month we have bank holidays (hurray), half term and a host of things to do in London from treasure hunts to flower shows, Vikings to knights and artists and scientists.

Lap up our 20 things to do in May and lock in those calendars! 1 Follow the story of Queen Kraka, peasant girl, warrior, and leader.
