You will need to level the tripod, then level the camera. The camera back should be perpendicular to the ground. Assuming the tower is straight, it will then be straight on the image. Because the camera is pointing straight ahead, the top of the tower will likely be cut off.You then use front rise to bring the field of view up so the tower is in the field of view.
One could take a straight image of a building with any camera with a wide angle lens by leveling the camera, but the bottom half of the image would be below the horizon and not very useful, so that's why a camera with front rise is traditionally used.
A book like Steve Simmons' "Using the View Camera" is helpful to understand positioning the camera and using movements.
