I heard Bill Nye The Science Guy talk about his father wanting to set
out marks for the Washington Monument.
Great idea, but the problem was the fuzzy shadow.

Can someone please tell me what is the world’s 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 world’s 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,
