The first transmission received in North America by Marconi was at Signal Hill, St. John's, Newfoundland and Labrador in 1901; Glace Bay, Nova Scotia was the site of the first such two-way transmission, in 1902.[2] One of the station's most notable roles occurred with the sinking of the RMS Titanic in April 1912. Operators at the station were able to alert the RMS Carpathia so that the rescue of some of the Titanic{{'s}} passengers could be effected. The station was shut down in 1917 in part over concerns about its use in World War I, but also because its towers were threatened with erosion. In 1920, usable materials and equipment were removed from the site, and it was abandoned. Erosion has taken its toll over the years since then,[3] and there was little left as of the date of the National Park Service brochure.[2] No trace of the site remains as of September 2014; the sea has claimed it all.{{citation needed|date=September 2014}} Marconi had moved the station to Chatham by 1912 and the Titanic and Carpathia communications were done from there. There is debate of whether the Wellfleet station was ever put into commercial operation. The site was listed on the National Register of Historic Places in 1975.[1] GallerySee also{{commons category|Marconi wireless site in South Wellfleet, Massachusetts}}
