Yes, there is one. It sits high stop a hill (400 meters altitude; highest point in Uruguay is 500-something) on 600 hectares (almost 1,500 acres) of beautiful barren hills. Inspired by a vision of a visiting lama, started a dozen years ago, it sits basically in the middle of nowhere.
We went in a minivan with a local tour company, at the suggestion of friends with whom we did a bus trip to northern Argentina a couple years ago.
Interesting way to spend a day. Not something I’d be in a hurry to do again, nor necessarily recommend as a must-do. But different – which alone gives it points in a country that is, for the most part, anything but exotic.
