Base and Meridian

Stand at the center of Salt Lake City.

Often overlooked, the Base and Meridian is a small statuette on the southeast corner of Temple Square. On August 3, 1847, this location was fixed as the point from which all city streets were named and numbered.

Salt Lake City’s grid system originates from here, making the coordinates 0 East, 0 West, 0 North, and 0 South, according to the system. This location was chosen during the original survey of “the Great Salt Lake”after Brigham Young designated the centralized temple site on July 28, 1847. The grid system is still used today in almost every city and town across Utah.
