City officials have put up ropes between buildings in the downtown area to assist pedestrians with managing the strong downdrafts. Since 1986, Punta Arenas has been the first significantly populated city in the world to be affected directly by the thinning ozone layer. Its residents are considered to be exposed to potentially damaging levels of ultraviolet radiation. History Two early Spanish settlements were attempted along this coast (on the Straits of Magellan). The first was founded in 1584 and was called Nombre de Jesús. It failed due to the harsh weather and difficulty in the settlers' obtaining food and water, and the enormous distances from other Spanish ports. A second colony, Ciudad del Rey don Felipe, was attempted about 80 kilometres south of Punta Arenas. This became known later as Puerto del Hambre, which translates to Port Famine. Spain had established these settlements in an attempt to protect its shipping and prevent piracy by English pirates, by controlling the Straits of Magellan. An English pirate captain, Thomas Cavendish during his circumnavigation, rescued the last surviving member of Puerto del Hambre in 1587. Penal colony In 1843 the Chilean government sent an expedition to build a fort and establish a permanent settlement on the shores of the Strait of Magellan. It built and commissioned a schooner called Goleta Ancud. Under the command of John Williams Wilson, Chilean Navy, it transported a crew of 21 people (captain, eighteen crew, and two women), plus cargo, to accomplish the mandate. The founding act of the settlement took place on 21 September 1843. The fort was well-positioned on a small rocky peninsula, but the location could not support a proper civilian settlement. With this in mind the Military Governor, José de los Santos Mardones, decided in 1848 to move the settlement to its current location, along the Las Minas river, and renamed it Punta Arenas. In the mid-19th century, Chile used Punta Arenas as a penal colony and a disciplinary posting for military personnel with "problematic" behaviour. It also settled immigrants there. In December 1851, a prisoners' mutiny led by Lieutenant Cambiaso, resulted in the murder of Governor Muñoz Gamero and the priest, and the destruction of the church and the hospital. The mutiny was put down by Commander Stewart of
