What's on Family fun Family Discovery Morning: Radical Romans Our free Family Discovery Morning trails take place on Thursday throughout the school holiday with plenty of opportunities for arts and crafts along the way. Without the Romans there wouldn't be a city called St Albans, or an amazing Cathedral on top of the hill! Explore the Cathedral and the stories of one of the largest Roman cities in Britain on our Roman themed arts and crafts trail. These events are aimed at children 3-11. All children must be accompanied by an adult.
