Yorkshire was the stronghold of the Knights Templar, outside of London, and they once owned a manor in Etton. The site, which they owned until until 1308, was the only religious house of the Templar in the East Riding. It is no longer visible, but excavations in the 1960’s suggest a large complex with granaries, a hall and a brewery. This important archaeological site is located to the north of Bank House at the western end of the village.
