A hamlet of Mid-Argyll, Inverneill (occasionally Inverneil) is located at the mouth of the Inverneill Burn, on the western shore of Loch Fyne, 4 miles (6.5 km) south of Lochgilphead. Inverneill was amongst lands granted to Colin Campbell, 1st Earl of Argyll (c.1433 - 1493), in 1480. Inverneill House is now but a fragment of what it once was, representing a battlemented three-storey wing of the original house, which was added by Lt. Col. Duncan Campbell in 1890. The original house dated from the late 18th century but was demolished in 1955, the same year Inverneill passed from Campbell hands. John Lorne Campbell was a scion of this house. A Campbell Mausoleum (1802) lies in woods to the west
There is also fine walled garden, dating from 1790, which faces onto Loch Fyne and was said to produce some of the finest fruit and vegetables in Scotland. This incorporates two cone-roofed towers in its walls. The segmental-arched Inverneill Bridge dates from 1770.
