A distinctive example of Romanesque architecture, it was added to the National Register of Historic Places on October 29, 1982.

It is a single-story masonry structure, built of stone and brick, and set on a full-height granite basement.

It is roughly in the shape of an H, with projecting end wings, and a complex hipped roof line.

The building corners and window openings are quoined in smooth granite, while the basement level is of rough-cut granite, which transitions to smooth stone up to the sills of the first-floor windows.

It replaced Gardiner's first station, which had been built just to the south when service was inaugurated to the city in 1852.
