"Outstanding historical site and home of Earls of Ross. Recommend half a day for this visit. The self guided museum tour is what we did and it was excellent. We went outside, walked around the gardens and saw the telescope. You need a few hours to spend in the gardens and you could do lunch there or bring a picnic. excellent educational value. Th third Earl of Ross designed built and used the telescope and the fourth Earl of Ross invented the steam turbine."
