The Eskdalemuir Observatory is a UK national environmental observatory located near Eskdalemuir, Dumfries and Galloway, Scotland. Along with Lerwick and Hartland, Eskdalemuir is one of three permanent geomagnetic observatories in the United Kingdom.
Built in 1904, its remote location was chosen to minimise electrical interference with geomagnetic instruments, which were relocated here from Kew Observatory in London in 1908 after the spread of electric tramcars led to excessive electromagnetic interference there.[1]
