Plan Your Trip What's on Summer Reopening! Open Days We're now open on Sundays from 10 am to 3pm! We will be open every Sunday and Bank Holiday until September. Admission is free throughout the summer. From this weekend, we're opening some of our indoor exhibitions and you can enjoy a walk around part of our fascinating site. There will be light refreshments available and we have plenty of picnic space. We're sure you'll have a great visit and we ask that you make a donation to help us cover our costs. Please note that we won't be able to offer our usual activities and performances this summer due to the impact Covid has had on our organisation but we're looking forward to welcoming you back to enjoy our spaces in this informal way. Please check before you travel as pre-booking will be required. Last admissions at 2pm. Sorry, we can't allow dogs on site. Tickets will be made available to book the weekend before. We're sorry, but due to unforeseen circumstances we're unable to open on Sunday 1st August. Tickets will be made available for the next Sunday opening as soon as we can. Keep an eye on our website and please be aware that the tickets book up quickly. Sorry, this event is now sold out.
