This article describes a millennium project involving the construction of a tower, 'La Meridiana', near Rome, to house a series of internal sundials. The author designed 10 dials for the walls and ceiling, read by sunlight projected through openings or reflected by a mirror. An experimental dial at his family house achieved accuracy within 10 seconds. The project aims to demonstrate precise time and date measurement, zodiac, altitude, and azimuth, using novel methods for declination, horizon, and meridian establishment.
