How did science help to defend a castle? Discover the medieval engineering that powered trebuchets. Have a go at making and firing your own mini model. This is a relaxed SEND session of the Trebuchet Challenge activities running 19 - 22 August. Booking is required to keep numbers at a relaxed level. You will first enjoy watching some interactive roleplay with our team. You'll then get to have a go at the activities! FAQs How can I contact the organiser with any questions? Call 01924 302700 and leave a message or email [email protected]. We will respond as soon as possible. This number is monitored during office hours: Monday to Friday, 9 to 4. (It is not monitored at weekends and on bank holidays.) Do I have to bring my printed ticket to the event? No, we will have your details at the door.
