State/Province:  Maryland Country:  USA
Dial Type:  Vertical Condition:  Fair
Latitude:   38° 59' N Longitude:   76° 43' W
Location:
  • Sacred Heart Chapel, 16501 Annapolis Road (Route 450), up the road east of Sacred Heart Church. Behind the trees, 1 km east from SR 3.
 
Description:
  • A small vertical stone dial with a weathered wood gnomon is mounted with iron brackets to the wall of Sacred Heart Chapel. The dial is about 26 inches wide by 16 inches high. The inscribed longitude of 00 deg 20 min East is correct for the United States Prime Meridian which goes approximately up 16th Street in Washington DC. In 1853, fire destroyed everything but the walls of the chapel; it was reconstructed in 1858. The present stone dial is reported to have been made by Francis J. Deutsch, Sr., replacing and duplicating the original. See NASS Compendium Vol. 5, No. 3, Sept., 1998. The whole dial is now covered with white paint and the gnomon which is set at 42? is placed upside down. The wall is 7? SE but the dial was designed for true south.
