Find the location of the tower

Find the location of the tower

Engineering: 22

You analyse all the relevant data that the land can provide you to try to locate where the tower was built. After several hours of calculations, you deduce that the work had to be done about 40 metres east of the vestiges of the first construction. Aubrey and his team thus dash into the works. Next morning you are awakened by the shouts of the Falconers who have found what seems to be the ruins.
