Iberia

We had a nice dinner tonight with son M. and his family. Celebrating his birthday last week.
The restaurant had been Spanish in the past, but was now Portuguese.
The map on the wall, a jigsaw puzzle, was puzzling me. Not because it was not pointing to the North. No, it were the coordinates at the bottom left.
4000°N? How often around the earth would that be?
Obviously the decimal commas (or points) were left out, it should read 40°N, 4°W. What relates to Madrid in the middle of Spain.
A bit weird for a Portuguese restaurant, but also a positive sign.
