A strip buttress would be very close in relation to a flying buttress.

The key is the arches which are strengthened by the masonry and became a popular medieval design, and were internal. (satguru).

A strip buttress is a vertical architectural embellishment set out against a wall. It doesn't actually serve a purpose other than giving a structure architectual interest, whereas a flying buttress lends support to a wall.

A good example of strip buttresses is Crisfield Armory in Crisfield, Maryland.

"One strip buttress brackets each end of the side sections, capped with stone and with stone trims corresponding to the level of the stone watertable, the vertical center of the front wall and the dentiled frieze. The towers of the center section project slightly from the front wall plane and contain narrow windows at first and second floor levels, with some stone sills and flat brick arches. Each tower is flanked by strip buttresses capped with stone and trimmed with stone as in the side sections."
