Located underneath Marymount Road near the junction of Marymount Lane and Bishan Street 21, this station provides MRT access to residents living in the western part of Bishan New Town and Shunfu, as well as students and staff of the nearby Raffles Institution.
It serves nearby businesses, housing developments and Raffles Institution, Shunfu market & food centre, Bao Guang Fo Tang and Shunfu residential area.
On 10 February 2004, Marymount Road was temporarily closed for realignment works.
The options for station names were 'Marymount' and 'Shunfu', and in the end Marymount was chosen.
In this station's Art in Transit, Joshua Yang's artwork Superstring consists of individual pieces constructed with only one continuous line that winds around itself to let the viewer explore real and virtual spaces.
