If you can afford them (they can be shockingly expensive here in the states!), actual wooden shutters are very attractive and work quite well at cooling a home.
But, if you’d like to keep your view and stay cool, awnings are another option. They keep the window in shade and prevent heat from entering the home nearly as well as just blocking the window, while allowing the window to, y’know, keep on windowing.
If you’re somewhere without a ton of regulation or nosy neighbors, awnings can be made super easily with just some poles and tarps, or even a sheet of plywood depending on how much you care about appearance.
