Cuevas Del Drach, Majorca, Spain - September 23, 2016 The tour finished off with a concert played by a quartet of musicians in boats floating on Lake Martel, which is the largest underground lake in Europe, and one of the largest underground lakes in the world. We were not allowed to take photographs during the concert, so this is just a shot afterward.Ā This classical music concert has been performed since 1935 and is lit up with thousands of lights. It was an amazing experience.
