The Château de Tanlay at Tanlay (Yonne) is a French château built in Burgundy during the sixteenth and seventeenth centuries, famous for its beauty and the setting. The walls are of limestone under tall sloping slate roofs à la française, surrounding three sides of a central court with cylindrical towers at its four corners. The château is entirely encircled by its rectilinear moat and approached on axis across a bridge marked by paired obelisks through a gatehouse (illustration) built in 1558, which straddles the low balustrade and projects forward into the moat.
