The Castlefreke Post Office, also known as An Post Rathbarry, is located in the Rathbarry Shop in Milltown, near Clonakilty, Co. Cork. It is an authentic village post office housed in a local shop. The building (built circa 1820) is constructed in a Gothic Revival style, characterized by its striking battlements and tower-like details. This style is closely related to the architecture of the grand Castlefreke Castle, the ancestral home of the Evans-Freke family.
