Can someone please tell me what is the worlds largest sundial? If a vertical tower, how high above the ground is the nodus? I have been consulted by someone who is claiming that a tower he wants to use as a sundial, which is 162m tall, will be the worlds largest dial. There are many issues with a dial of this size, which will be explained to him, but I would like to know about sizes of other large dials, please. This is not just a tall building casting a shadow, but one where there are hour markings on the ground.
With best wishes to you all, Jackie Jackie Jones 50° 50 09 N 0° 07 40 W
