octangular

Its form is octangular, having a strong butment at each angle, surmounted with pinnacles.

There between octangular towers loopholed and finished battlement style was a covered passage suggestive of Egypt.

West of the Coro are two bays of nave, over the western of which rises the lower part of a rich octangular lantern.

It consisted of three octangular compartments, each supported by eight slender columns.

There is here an ancient octangular font, ornamented with shields, angels, &c.
