Points of orientation - Las Ventas by El_Sueco
As you can see from this picture, the bull-fighting stadium Las Ventas (to the right in the foto) is close to this great bow construction.
When you will come driving on the M30, you will pass under this traffic congestion where I am taking the picture, and you will know you are at the Ventas (which also is the name of a metro-station close at hand)
