During public opening hours visiting our sites is free for teacher-led groups and we have lots of resources to help you focus the visit. To ensure that you get the most out of your time on site we recommend that you do a pre-site visit. Have a look in the online resources section for downloadable trails. Even if you don’t need any input from our staff please let us know you are coming so that our sites don’t get overcrowded. Have a look at our booking section for more information.
