Windmills sound great, but the issue with them is that they're usually surrounded by flat land. A while ago, we went to see this one: https://maps.app.goo.gl/EnnExo2wyQ2WMFqZA It was quite nice; the owner has an airstrip next to it and parks his plane right under the mill, but it's in the middle of fields. Looking at the mill was great, but the view from it would be less interesting... I think.
