The Duke and Duchess of Cambridge have touched down in Belfast for their previously unannounced two-day visit to Northern Ireland. William and Kate – or Baron and Lady Carrickfergus as they're known in Northern Ireland – spent the day meeting locals and carrying out a string of engagements.
Day one of their trip had a strong focus on the positive impact that sport, nature and the outdoors can have on childhood development, and improved physical and mental health for all.
William and Kate started with a visit to Windsor Park, where they learnt about the Irish Football Association's community Football projects, and how sport can play a role in bringing communities together.
