The GaithersburgLatitudeObservatory, located in Gaithersburg, Maryland is one of the system of six International LatitudeObservatories, and (as of 2004) the only National Historic Landmark in the City of Gaithersburg.
The observatory’s roof was designed to part in the middle on two sets of tracks to expose the reflecting telescope inside to the night sky.
The GLO was constructed by Edwin Smith, Chief of the Instrument Division of the U.S. Coast and Geodetic Survey.
The railroad was brought to Gaithersburg in the 1850s, with the encouragement of the Gaither family.
In 1899, Gaithersburg was selected as one of six global locations for the construction of an International LatitudeObservatory.
Gaithersburg is served by WMATA Metrobus and Montgomery County Ride-On bus service and two MARC stations on the Brunswick Line, at downtown Gaithersburg and at Metropolitan Grove.
