On October 20, 2020, local time, in Imotski, Croatia, a mysterious artistic sign appeared at the bottom of the Blue Lake when the water was receding. The sign can be observed with the naked eye anywhere on the lake.

From Sunday to Monday night, the Blue Lake began to store water, and the sign was hidden under the water and disappeared.
