The sheep belonging to Sandavág was rowdy. So they hired Hendrik Thomassen a renowned sheepherder to go to Slættanes to tame the sheep. He liked the place so that he asked if he could settle down there. The people of Sandavág did not like settlement at Slættanes and fought him for as long as they could. The county official a man called – Pløyen – finally came to Hendriks aid in 1835 and helped him move to Slættanes.
The following years more and more people came to settle.
The priest would only visit once a year so if someone died he would give them their last rites the next time he was there. The mail had to be carried over the mountain from Sørvágur. Any goods they needed they had to row over to Vestmanna a buy it. In 1933, almost a hundred years after settlement they finally got a school built. Later they built an alter inside the school so it functioned as a church as well. The teacher Napoleon Petersen arranged for a swimming pool to be constructed in the nearby gully.
At its height in the 1940’s there lived 75 people in the village. What sealed the end of the village was that the power company informed them that they should not be expecting electricity.
In 1964 the last family moved away from Slættanes.
