The station opened on October 14, 1966, as part of the original network of the Metro; it was the western terminus of the Green Line until the extension to Angrignon in 1978.
In August 2016, the Dawson exit was closed for refurbishment. In January 2017 the Cabot Square entrance was closed for major renovations and also to make the building unwelcoming to drug use and violent gangs on the premises
As of 2020[update], work is underway to make the station universally accessible.[5] Phase 2 of this project has begun in 2024.[6]
The station is equipped with MétroVision information screens which display news, commercials, and the time until the next train.
