Klimt’s landscape-themed paintings were mainly produced during the artist’s summer sojourns. In the years 1900-1916, Klimt and his partner Emilie Flöge, an avant-garde fashion designer of Vienna, spent summers by Lake Attersee in Land Salzburg. Staying in nature freed Klimt from Vienna’s cultural and political confrontations. During his sojourns, Klimt created eleven landscape paintings with the lake motif including four variants with Krammer Castle. Water Castle is reminiscent of the subdued colours of the artist’s earlier compositions. The contrast between the materiality of things in the upper part of the painting and their flickering reflection in the water is the most charming feature of this Klimt painting.
