A HISTORIC post office built in 1881 at the foothills of the Watagan Mountains in Cooranbong has hit the market.

The building - which is now a home - at 41 Martinsville Road was listed this week with Ellejayne Realty agent Ben Wrigley who is marketing the property for sale two years after he sold it to former antiques dealer and passionate history-buff, Lorna Charlton.
