The town and lake of Thun are the subjects of many works by Turner. Here he explores contrasting effects of strong sunlight and stormy skies, both illuminating and appearing to dissolve solid structures. The town's distinctive towers dominate the sky line yet the majority of buildings are merely hinted at as they are bathed in light. The brilliant reflection on the water and the atmospheric mountain range beyond contribute to the scene's sparkling vitality. It is similar to some of the coloured drawings Turner made during his last visit to Switzerland in 1844.
