In this series we pay tribute to the art we wish could visit — and hope to see once travel restrictions are lifted. As winter digs in across the country, I’ve been thinking of summer days in Europe. How pleasant to be back in sunny, southern France among the vineyards and hum of crickets, rather than trapped on our large island continent with little prospect of a return to Europe anytime soon. One of the highlights of my visit to that region in the summer of 2017 was the surprising Château La Coste, an art and architecture park in the heart of Provence, about 15 kilometres north of the university town of Aix-en-Provence.
