A new and very interesting, perhaps unique, dial has been added to the NASS
Sundial Register. The dial is delineated on the inside walls of a purposely
built tower. Indications include analemmas as well as altitude and azimuth.

Fascinating. Does anyone know it the analemmas were placed after observing the
