The Greek Revival armory building was constructed in 1843 with a $1,000 public grant from the Rhode Island General Assembly to the Kentish Guards for their aid in the Dorr Rebellion in 1842.

[2] In 1970 the building was added to the National Register of Historic Places.

The Armory contains a gallery of pictures featuring former members of the Guard.

The original charter hangs on the wall as a lasting reminder and a memorial to those men who organized the Kentish Guards in 1774.

The Kentish Guards Armory may be visited on Tuesdays, when the militia company meets, and Wednesdays, when the fife & drum rehearses, both around 8:00 pm (except during holiday periods) and by special appointment.
