Guyancourt QIBLA DIRECTION
There are many methods to find the Qiblah direction. One of the easiest ways is using compass. Qibla direction changes from city to city or country to country depending on the distance. From this site, you will easily find Qibla direction.
The red pointer indicates magnetic north. There is much difference between the deflection angle with magnetic north. Therefore, we give two different Qibla direction angle. For Guyancourt use the angle 120
Note that there are no large metal objects around. (Not even smaller metal objects). If there are any larger metal objects, such as cars, please apply the process 10 meters off. Set your compass as the red needle shows the North. Then you can turn to 120° and pray to the Allah.
