"Great hidden spot for a walk and little escape
Hope it doesn’t get too busy"

"Historic landmark with a huge significance, hidden away where you may not expect it. We went on a weekend, daytime, free entry. Plenty of parking, and free too. Both buildings were open and staffed by volunteers, they were all friendly and welcoming but the young students didnt really have much knowledge of the place which was a shame. I would love to come back for stargazing."

This was an extraordinary experience and I cannot thank the volunteers enough."
