For the 11th edition of the INmusic festival, held in May of 2016 at Jarun Lake in Zagreb, the city erected a 30 meter replica of the Wardenclyffe Tower, also known as the Tesla Tower. The tower contains 3,500 zinked metal parts replicating the original structure. The original was 57 meters high with a spherical top 20 meters in diameter, and was designed by Nikola Tesla in New York between 1901 and 1902 to wirelessly transmit messages and images across the Atlantic. Rumours say the original tower was destroyed in 1917 to prevent it from being used by German spies, others say it was scrapped to cover unpaid debts.
