Montague Street is lined with elegant early nineteenth century terrace houses, which are grade II listed. These four-storey properties are still adorned with cast iron railings and balconies on the first-floor windows. Although some have been converted into hotels or offices of the British Museum, a few properties remain in residential use. On the east side, a gap between the two terraces is filled by some decorative iron gates dating from 1899, that give access to a private communal garden behind.
