I have several files in WKT format, and something strange happens when I import them in QGIS (v.2.18.1) (layer->add layer->add delimited Text Layer), files containing lines and polygons are correctly located on the map, but those containing points are not, and the same CRS is used (EPSG: 4326, WGS84) for all files.
The examples that I put correspond to data an area of the north of Spain, and as you can verify, the lines and points are loaded in that zone, but the points go to the Indian Ocean, in the coast of Tanzania.
Here you can download the wkt files used (are only 65KB zip file) : wkt_example.zip file link
It is very strange, because the coordinates are good, if I take a point of the file that is misplaced, and I copy the coordinates within google maps, the point is correctly located in the north of Spain.
Here I put some lines (only the first ones) with the content of these files (utf-8).
