Rye, New Hampshire was the location of the first undersea cable connecting the United States with Europe. The Cable Station was located at the end of Old Beach Road which is also where you can see the remains of the Sunken Forest during extreme low tides.
The cable was laid by the steamship Ambassador in 1874 and was capable of transmitting morse code. The cable went from Rye to The Isles of Shoals to Nova Scotia and then on to Ireland.
The cable station was manned by four workers around the clock two to receive messages and two to send messages. The remains of the cable is still in place and can be seen by scuba divers.
